Microsoft Outlook - email and calendar

Microsoft Corporation



This app was last updated on: Jul 17, 2017
TapNova doesn't recommend this version of the app.   
New in version 2.34

Big changes ahead this week. We’ve completely redesigned how email conversations look inside of Outlook to make reading and replying easier and faster than before.

Here’s an in-depth look at what changed:

- We now show all messages uncollapsed and provide clearer separation between messages in a conversation for easier scanning.
- When tapping on a conversation in your inbox, we will now automatically position you where you last left off. No more scrolling around to find the message you need to read first.
- You can now see and scroll through previous messages while replying to a conversation. Tap in the quick reply box at the bottom of the screen to try it out.

This feature is progressively rolling out for, Gmail, Yahoo and iCloud accounts. Office 365 accounts will follow soon.

Let us know how you like our new conversation view. Feel free to send us any comment or question through our in-app support in Settings, we’d love to hear from you.


“The best email app for the iPhone.” - The Verge

Meet Outlook for iOS, the app that helps millions of users connect all their email accounts, calendars and files in one convenient spot. Newly redesigned, Outlook for iOS lets you do more from one powerful inbox.

See what matters most first with the Focused inbox that keeps the important messages on top. Switch between your emails and calendar to schedule your next meeting or share your availability with just a few taps. Or grab a document from your Files list and attach it to an email seamlessly.

Outlook for iOS works with Microsoft Exchange, Office 365, (including Hotmail and MSN), Gmail, Yahoo Mail, and iCloud.


Here’s what you’ll love about Outlook for iOS:

Seamless inbox management

- Swipe gestures to quickly schedule, delete and archive messages.
- Smart filters to help you sort through your inbox.

Easy access to calendar and files

Still Inoperative

Email and calendar functions that do not connect to my contacts. How is this productive? Every email client I've used always connected to my phone and gmail contacts. This app does not.
PalmtreePanda on 7/21/2017
The new updates have made replying, replying all and forwarding a difficult task. Now I have to go in and edit recipients which is a cumbersome feature. Also don't like the removal of easy flagging. Gave you a couple of stars for the new look and ease of switching between email accounts. Please readdress the replying features. Before it was press 1 easy to find arrow and type. Not it's 3+ steps. Thank you
Latest update HORRIBLE
eca712 on 7/21/2017
This app is almost completely unusable after the latest update. Why the hell would you hide the forward and flag options in tiny little drop downs under two different three-dot icons? And why do I now have to devote time to remembering that "Add a message" just means "reply"? Was "reply" too hard for people to understand? I'm going to have to find a new email app if they don't reverse these changes. So stupid.
Update broke the app
Dwight Specht on 7/21/2017
The last update now prevents the app from sending email with office 365.
Ain't what it used to be!
jeffscott on 7/21/2017
Everything was fine for quite sometime. But since this latest update, I'm prompted to enter my password for two of the connected accounts at LEAST twice a day! Wassup Microsoft?!! If it ain't broke, don't fix it!
Old cop56 on 7/21/2017
The best, working app!
Does not sync calendar with exchange if I get last minute invite and I'm not on wifi.
dtoader on 7/21/2017
Does not sync calendar with exchange if I get last minute invite and I'm not on wifi. This is a major flaw. I had a meeting invite last night at 9 pm and I opened the app waiting for it to come through. No dice. It didn't show on my calendar until this morning when I got on wifi and opened the app. To me, this is a show stopper.
Update adds more steps. Poorly conceived.
2-DannyDeuces-2 on 7/21/2017
You can no longer reply/forward or flag with a single click. Their poorly conceived backwards "update" adds extra steps to a fast paced 2017 on-the-move worker. Very poorly planned. Shaking my head.
Prodctivity Killer
Rmotcy on 7/21/2017
Today my company decided to move away of an Exchange server using the iPhone native app in favor of Outlook so this is my first impression. The only Pro of Outlook app is the Focused folder. Other than that, the contacts are not being handled as it should with the native iPhone contacts. It is a one way only. I have not seen the notes yet, but overall the performance is not good. The thread view doesn't allow to mark a particular item on the thread as unread, at least is not intuitive. Changing from thread view to simple view took about 5 minutes. Will update after a week of usage. * Update * I have changed the title of the review from "Need Improvement" to "Productivity Killer" and removed the last star I was able to remove. Besides issues above the application is buggy. Half the time that I need to mark an email unread doesn't work from the list view, nor from the ... inside the email. The text editor removes the leading space when you come back to replace a misspelled word creating a new bigger misspelled word. So you better type it right the first time or you'll be wasting time editing your text. If your wise IT department also opted to have Azure authenticator app, you're end up double verifying your identity twice a week waiting 2 or 3 minutes to have your SMS for the double checking method. If you have an iPhone and iPad you need to do it on each, twice a week. I had to google it how to forward an email from my sent folder. The option is buried inside the email only when open the Sent To: list. Now that I know it takes 5 taps to forward an email vs two on the native email. The native app allows me to do "multi-tasking" by placing a composing email on hold (not draft) while navigating other emails to select-copy then taping on the pending email to paste information. On Outlook for iOS requires you to save the draft, then come back later with way too much more taps. I would advise Microsoft to do what they're do best (doing desktop applications) Outlook is still the best for desktop but it is loosing ground if they continue trying to do something that is already excellent on the iOS: Focus on your strengths! I'm thinking of uninstall it from my personal device as I guess my company doesn't want me to check the emails anymore with all the added burden required to use this application.
Was great, now not so much
FankNBeans on 7/21/2017
With this latest update, Microsoft has decided to dumb down Outlook from a business tool to a social messaging app. Reply, Replay All and Forward have been standard features since email was invented. Now Microsoft has decided to make them into obscure to find features. I will be looking for another mail app that understands its audience's needs. Hey Microsoft, were not all millennials!
Good app - suggestion please..
jbit87 on 7/21/2017
Just want to follow up, I hope I've been heard! Our Sales Team uses Outlook for iOS and MSFT Dynamics and if these two could sync when we email or call, along with the iOS contacts, our work flow would improve greatly. Love this app but please need ability to sync with MSFT Dynamics. I'd love to be able to open an email via dynamics and vice versa, make auto record of communication efforts/activity - emails, phone calls, etc. Working in sales, this is needed! Suggested this in user voice too. Also...Your dynamics iOS app is a bit buggy. Hope you guys are working on an overhaul in the near future.
Best iOS email client
drkemp1 on 7/21/2017
My last review in February was one ⭐️. Since then, there has been dramatic improvement and in performance and functionality. Microsoft provides excellent support and frequent updates! Outstanding app!!
Add a message feature
iBourbon on 7/21/2017
Love the quick add the message feature at the bottom of emails. Very very easy to reply to emails. Good job!
New update has destroyed this app.
Ando Ano on 7/21/2017
The new update has made this app slower than any I've seen before. I uninstalled and then installed again, but it's still crazy slow. Support, please help or update. (Old review) Good app. But needs a better way to view email folders. I organize all my folders/customers by company name. It takes me 5 minutes to get to a customer/company name that starts with the letter T. Because you have to constantly scroll through. They need a drop down with Letters so you can quickly get to the folder. Also needs better contact management where all contact folders can be viewed and accessed.
Unusable :-(
CMJRoss on 7/21/2017
I was soooo hoping this would be a replacement for the native IOS mail system, but it absolutely cannot be until Microsoft fixes the shortcomings. My main issue is that I cannot access my Exchange messages that are older than one month old. Seriously?? Who functions like that? My Exchange is my business email, and I've never seen a business that functions in a window of one month. So...I've since stopped using the app, and I've told my IT guy and my Exchange hosting company to warn other customers away from this app, whether it's for business use or personal use.
Getting better with age.
Slugrex on 7/21/2017
Best email app for iOS. Faster than them all. Feels light and nimble. New conversation view is much improved. Still room for improvement. Needs selective sync capabilities to pick and choose what to sync (calendars, contacts, etc) or just fully rely on iOS for those functions.
Please add more steps to everything that only had one
Bstone2577 on 7/21/2017
Reply/Forward arrows. Bring them back. One button to push. Now 3-4 steps. Terrible idea. Fire whoever came up with it. Very simple. Do not add more steps to do something on phone app that is supposed to be for ease of use. First thing anyone should think of when changing anything. I have a hamster smarter than that.
Latest update unusable - crashes constantly
Jricle on 7/21/2017
Title says it all. Cannot use on either iPhone or iPad. I try opening the app, then it immediately freezes for a while, then crashes. Please fix.
Update hard to use
topvet on 7/21/2017
I find the update harder to use. I tried to forward an email and none of those icons were on the email or at the bottom.
New update a step back
privateok on 7/21/2017
Where did reply and reply all go? More clicks to do basic things? Backward. App is also slow and freezes now. Sluggish. SAD! Going back to native mail app... Or can someone recommend an alternative? This is now unusable.
New update
Henderson42420 on 7/21/2017
With the new update the app keeps crashing. I can see my email come through but it does not allow me to open the app.
Updated 7/2017 - they ruined it
noah_nyc on 7/21/2017
Someone got the bright idea to hide the Reply, Reply All, and Forward buttons. Yes, the three most common functions in email. You now need 2 clicks to reply instead of 1. And why? Because MS wants to bend us all to the "conversation" paradigm, so they can pretend to be a chat app, because they're scared of Snap or whatever. You don't reply, you "Add Message", which means typing into a tiny field and automatically reply-all. So they've made the most common good use cases harder, and the most common email fail - accidentally replying all - easy. Not sure which product manager bro came up with this one but whoever they are, they ruined the app. For no reason at all. Nice job.
Huge Fan but you complicated the reply option
Jrq1010 on 7/21/2017
I am a huge fan of this app and have been for a while. However, this new version has added steps to responding or forwarding that seem unnecessary. Please bring back my arrows.
New navigation menu is bad
Shubhan Chemburkar on 7/21/2017
The New navigation menu is horrible to use. Not intuitive. • The icons for accounts are too large. • I can't figure out which icon is for which account, as all my accounts have same SC abbreviation. Bring back the old navigation menu, possibly via a option in the settings. The rest of the new design update is bearable.
Bring back forward button
Ralph765356 on 7/21/2017
I love this app, but please don't hide the forward button! Also, seems on 365 I can't accept meeting requests.
Useless With My Work Microsoft Exchange Account
13RottenApples on 7/21/2017
The IOS mail app on my employer-supplied iPhone works MUCH better than the useless Outlook app. Feature requests seem to vanish into the black hole of the Microsoft universe. This app causes my exchange account to lock each time I change my domain password. Myself and many others have added a feature request to have the ability to log out of the app, but Microsoft has shown no interest in adding this very simple feature. So, I have deleted this useless app and returned to the native IOS mail app. Have a wonderful day! 🍺🍕
New format is awkward
LSMN on 7/21/2017
I don't like the new format with the reply window looking like a text message. Hitting reply or reply to all or forward needs to be an easy and quick click... but now steps are added. I don't use gmail for a reason - don't like the format - but now Outlook is becoming more like gmail. Boo!
Performance issues
YashAnantha on 7/21/2017
Most of the times when - there are around say 20+ emails in notification pane and I click on a single email to read that, it opens the app, blank white screen and takes a hell lot of time, sometime app just moves to background? Giving an impression that it crashed, but it exists in background, I have to go to list of running apps view and open it again...
Going Great
Never Know on 7/21/2017
Going to take a little bit to break muscle memory from tapping reply, but in a good way! Thank you for thinking about flow and the actions performed. Would like to see the following: -HTML signature, allow for pictures -Ability to add bullets to an email - Meeting Invite: Would be amazing if location would pull from room list or if when you added an attendee that was a room (resource) it would set the location.
New Update
iHeather on 7/21/2017
I normally LOVE this app...but whatever update just happened has slowed this down to a crawl. Also, what happened to the settings button? Please, fix whatever you did so that I can go back to loving this app which normally helps me to be so very efficient.
Hidden Reply and Forward Buttons
parkhurst89 on 7/21/2017
Very disappointed in this new UI. Requiring the user to click get to Reply and Forward and turning the default of 'Add a message' into Reply All has made the bottom half of your UI useless. The business world hates Reply All. Why would you make that the default?
Great update - look and feel
Dwilski on 7/21/2017
Wish we had priority setting. Can this be looked into?
New conversation feature needs to go away
fgrillo3030 on 7/21/2017
The first thing I googled this morning was how to turn off the new conversation feature. I don't want to join the conversation. I just want to be able to reply, reply all or forward. You have created annoying steps to achieve basic functionality of an email app. Instead of just hitting the "forward button" now I have to click on "add a message" then I can select "forward" then choose recipients. Too many clicks to do what had always available. Please provide a way to turn this unnecessary and time consuming feature off.
Messed up reply and forward
BrianGGG on 7/21/2017
The latest update made it difficult to reply and forward. Dumb.
Reply All as new default - why?
leitiNY on 7/20/2017
I use this app exclusively for work email/calendar, as it seems to work significantly better keeping things in sync with exchange. However, usability is not getting better. The latest update removed the Reply/Reply All/Forward Buttons and moves them into a submenu, adding more clicks. When responding to an email, Outlook now essentially defaults to Reply All now, unless changed manually. It also doesn't make this obvious - you will only see who you are sending your mail to, if, once again, you check manually. This seems to be a change purely for the sake of changing something, without considering how users might use the app. At least, Microsoft should give an option to us classic style (or whatever marketing wants to call it) to turn off these new features (and collect data on how users actually use the app). After being a user from the day it launched, and loving it until now, I will no longer use this app. The risk of sending a quick individual reply and inadvertently copying half of my company is not worth the convenience.
Latest upgrade constantly crashes and lags
DeanZ428 on 7/20/2017
The latest upgrade (just a day or two ago) simply will not work on my IPad or IPhone. It either won't open at all, takes about 20 seconds to open and then immediately shuts down, or opens and is mostly unresponsive. After seeing post from developer, uninstalled and reinstalled on both devices. Cannot even file the report they suggested, as it simply will not function. Incredible lag in typing, nothing is responding properly, cannot scroll emails. Argh!!
Broken email experience
TheloniousMunnk on 7/20/2017
The new view makes email threads feel like chat, with important reply and forward buttons hidden. Will likely dump the app soon if they don't add a way to toggle this new "improved" view off.
Latest Update Has Sent Me Back to iOS mail
CO Shooter on 7/20/2017
Unlike other reviewers here, I find the latest update to be "clunky" and require too many key strokes to accomplish simple tasks (e.g. replying to a message). I also find the updated version to load slower and a lag time for the keyboard. I have moved back to iOS Mail.
victoria, former outlook user on 7/20/2017
I have been logging into the same account for years, every single day. The same email address and always the correct password. Now, suddenly today, I can't view my email on the website. Desperate, I downloaded this app and it keeps asking for my password. I know my password. I used to twice today. I can't get into my email. There is no clear instructions on how to get in. I'm so frustrated. So this is my review. So far this app is useless. And apparently so is the email service.
Good App, but...
Rew61 on 7/20/2017
When I open the app on mobile device the email folders are fully expanded. It doesn't appear there is anyway to collapse them, much less default to a collapsed view. Also, being able to reorder the folders on a mobile device to match my desktop would be cool.
Clutter Folder
CD-LUV on 7/20/2017
Before the update, I could create a list of favorite folders or at least customize the list. Now I can't seem to control the favorite folders list. I'd like to move the clutter folder up into that list, but I can't.
Reply and Forward
Shabba Congo on 7/20/2017
Really really hate what you have done in the latest release. If I wasn't forced to use for business I would delete the app!!!
Replying to messages is not easier!
SactoKing on 7/20/2017
The worse development for replying to messages. I have to tap twice to reply all or forward, the arrows were better. Editing the to line appears to freeze the app then a selection pops up to edit recipients. In what business world were the developers thinking this was going to work.
Spinning update
spinning update on 7/20/2017
The app shows "updating" since the app update. Did not have this problem with the previous version. Updated ios and restarted and have the same problem.
Good, dependable and works well on iPhone
Ss1183 on 7/20/2017
Good app.
Not really there yet
Nysteanders on 7/20/2017
This is an OK mail app but not close to the best ones and it doesn't really seem like Microsoft take it seriously. An example is that it's impossible to see shared calendars with this one, important for many business users. Outlook OWA is an alternative but that has other drawbacks like very little configuration possibilities. You can't schedule a meeting setting a different time zone either. Mail categories from desktop doesn't travel over to phone app. Nor does Drafts stored from desktop. I like the possibility to send availability from the calendar though but there's room for a lot of improvements still. Not really there yet.
Pneid on 7/20/2017
Horrible update. Takes forever to respond like the good ol dial up days.
Changes in latest version are awful
Snradio on 7/20/2017
Please bring back the reply, reply all, and forward buttons at the bottom of the email as you read them. The latest changes are just awful.
Stupid changes on last update
Klkkkkkkjjjjdjjjgssss on 7/20/2017
The steps needed to add or remove recipients to and email now is absolutely ridiculous.
New update is confusing..
Mark Saltrelli on 7/20/2017
Honestly this was the best email app out there however the newest update makes it very difficult to reply and or forward, or if you need to reply and cc or add another recipient. At this point it takes longer. I would honestly suggest switching it back how it was, because other than that it works really well.
