Version 2.78.0 crashes
Woodstockdad1 on 5/24/2018
This used to be a great app but with this “improvement,” the app just keeps crashing. Won’t even load. Sad.
Still fails ... and poor grammar too
drjwr on 5/24/2018
How can a company that makes a terrific app like OneDrive make a flop like this? MAIL: Mail remains inferior to the native iOS app. Since the awful and much-disliked July 2017 update, which attempted to turn Outlook into a slick social app, all mail handling is more laborious and unclear, with accounts identified by ugly colored circles and ridiculous initials, and a sliding shelf obscuring an inclusive view. If you are ADHD, you’ll love the multiple steps and continual flicking back-and-forth to check your mail, a process exacerbated by making the inbox the default for a mail account: When you check the important sub-folders for several different accounts, the flashing shelf back-and-forth is so dizzying that you run for the Zofran. In all honesty, if you want a MS mail handler, through Safari is a far superior way to check your mail. The app design is aimed at being cutesy rather than efficient. Cutsie? Try red, yellow, and blue envelopes for no open mail; or blue pencil with yellow paper proclaiming “Nothing in drafts. Start writing something fabulous”; or useless icons for appointments; or a calendar icon that tilts forward and backwards depending on days picked ahead or behind the current date. Ugh. CALENDAR: Nearly 10,000 users have wanted a real monthly view rather than the useless agenda/dot view, but we’re ignored. Hey MS, you bought Sunrise. This is a very lamentable and probably uncorrectable mistake embedded in the original design. What a calendar flop. POSITIVES: Are there positives? Only one: Integration with Office software. That’s it. I have to use the native app for mail; then switch to this app if a document needs work; then switch to Google calendar or Calendars 5 for a real calendar, to see a pattern of meetings over the coming weeks and month. FAIL: This app completely fails at what it intends to be — a single, integrated work app; and, in that regard, it’s as distant as could be from Outlook on the desktop. (PS The second sentence of “What’s New” needs punctuation other than a comma. As the sentence stands, it has a grammatically incorrect “comma splice,” and is a further embarrassment to Microsoft.)
Great App
JPDad007 on 5/23/2018
I enjoy the usability and display. Only reason I gave a 4 out 5 stars is due to the search capabilities. As with any email app searching for old emails is at times cumbersome. 5 stars on everything else, it’s a great app.
Gets Better Every Month!
Rigidfit on 5/23/2018
By far my #1 choice for the best email client!
Tried again - still utterly worthless
72bleh33 on 5/23/2018
I can’t stand the GUI and the way email is sorted in conversation view is opposite of the iOS app. Seems to be pretty buggy and just difficult to use overall. Typical Microsoft. Why bother with a sub-par app with no native integration. There will need to be a pretty compelling reason for me to try this app a 3rd time.
Almost perfect
Keinemal on 5/23/2018
Occasionally it erroneously puts something into the junk mail, but it’s great overall.
Works fast and well.
celeste archer on 5/23/2018
The MS apps for iPhone are great. Fast and they work. Works well with my PC
Never miss a meeting
Trail runr on 5/23/2018
It is so nice to be able to quickly see my calendar and know where I am going. Settings are easy to personalize. Love the filter for directed e-mails vs ads
App widget stopped working
Misha Reviewer on 5/23/2018
With the latest release the iOS app widget stopped working. It displays “Unable to Load“ error message. Would you please fix this.
MS Outlook
John_Amendall on 5/23/2018
Is my go-to e-mail program. After all, Microsoft IS the king of the jungle!
Buddy Duque on 5/23/2018
App Delayed
El-Felici-Ano on 5/23/2018
The application seems a bit delayed at displaying schedule dates. Leading confusion and head aches.
Huge step down from OWA
Yet another business user, on 5/23/2018
Floating Attachment button appears over send button on iPhone 7. Signature not included and can’t remove the “Get outlook for iOS” plug. Can’t view public calendars of colleagues. Huge step down from OWA app. Blech.
GameJinx on 5/23/2018
Make changes calendar items easier on a handheld device
No way to attach from Files app

No way to attach from Files app
sr maganti on 5/23/2018
Working good,useful
Outlook app
Steve 722 on 5/23/2018
I like Outlook mobile. BUT it took a step backwards when they removed the Contacts tab. Needs to work as close to Desktop as possible. NEEDS: -Contacts that can be browsed through. They had it but removed it. -needs to be able to pull up Contacts by Category. -Needs to be able to search Calendar.
Best to Worst
BOSS!!!!7 on 5/23/2018
What happened to this app? Used to integrate seamlessly with desktop outlook and saw no need for a change. Now it’s like my iPhone is a 3rd party. Here’s what happens. When I set up a new appointment on desktop it shows up on iPhone as an invitation with dashed lines around it. When I tap on appointment it asks for RSVP. When I try to RSVP the communication fails. Lately when I add a new appointment via the iPhone it takes 5-10 minutes to show up on the iPhone but does show up immediately on desktop. After it does finally show up on iPhone if I reopen and save it makes two appointments. Support has been no help. IS THERE SOMETHING WRONG AT MICROSOFT?
Ferramenta muito boa
Patrick Morais on 5/23/2018
Ferramenta fácil de mexer e muito boa visualização, sem contar com segregação de outras contas sem poluir a visualização.
Where is pin at?
Ray-che on 5/22/2018
I can pin conversations in the phone app. So not cool.
the app is ok yet I wasn’t able to find some options
mrnadia on 5/22/2018
First, you need to delete this terrible automatic signature with ad of the app, but that’s kinda common for all mailing apps. Second, is there a way to add a file from my iPad as an attachment? It only offers me some files from old emails and from google drive/dropbox. Very inconvenient.
Ghgcmndsdtpotfdsxert on 5/22/2018
Ok so there’s this file section on Outlook with a whole bunch of different files stored in it (I’m guessing this the section for files you’ve received and sent). I have a whole bunch of pdf files and jpg files from previous school years, but I don’t need the files anymore. I’d like to delete these files, but there’s literally no way to do it (at least not that I can figure out). I really need to delete these files, though, because Outlook is taking up over a GB of storage on my iPad, and I think it’s because of these files. If you could please add a way to delete these files, that would be extremely helpful. Or if there is a way and I just don’t know, can somebody please tell me how?
Design for play on 5/22/2018
I used this for my work email twice it was conveniently hacked sending out a ton of emails causing me to have to have the administrator to reset and get my email out of Microsoft hostage I have not had this problem not using this app and it conveniently happened everytime I reinstalled it that pretty much my giveaway that it’s not trustworthy
mcloven111 on 5/22/2018
It is not easy to distinguish emails I have read from the ones I have not. And also hard to separate email based on what has been open and what has not.
Can’t delete calendar events
wclaymore on 5/22/2018
Can’t delete my own calendar events. It gives me the delete option when I edit the event but it doesn’t actually delete.
172Capt on 5/22/2018
Sigh...this app has something new wrong with it every time it’s updated. Now, when you get an email and you’re in the app, you see the notification as usual, but when you tap on it, it says “this message no longer exists”. You then have to close the app, reopen it and you’ll see the email. So annoying.
It actually get worst after every single update...
abdone on 5/22/2018
I’ve been using this app for almost 2 years... it used to be so fast and reliable... I have 3 accounts, 1 office 364 and 2 Hosted Exchange and now, after the last update to switch from account to account (I don’t like having the “all mail view” ) I actually have to wait over 10 seconds to load the side bar to switch them! CRAZY!!!! It wasn’t like that befo
Very slow app on iPhone 6s
Edgargo on 5/22/2018
Slow to load up, created events do not show up right away in the calendar but few minutes later, same with emails sent, they do not show up right away in the discussion thread but few minutes later. This app (which I HAVE to use because of my company policy) is making my life very difficult!
Email signature formatting issue
Mr.L09 on 5/22/2018
Please allow use of better signature formatting and more space to view when editing.
Good once default settings changed.
r0lyp0ly on 5/22/2018
The focused inbox may be useful for some, but the organize by thread option made everything a MESS! Emails are out of order and sometimes missing from the thread. If I hadn't been checking it online, I wouldn't know the other messages were even there or what order they came in. Once I turned that feature off, it straightened out. The default swipe options are pretty terrible too, but thankfully this was all very easy to change.
Copy / Paste
Jburgo88 on 5/22/2018
Copy and paste in an email hasn’t been working for a while now!!!
Needs improvement
judyereese on 5/22/2018
While this good be a good app, it does have problems. Works generally well, but one major problem -- I have maybe 20 folders set up in my account to store email and only ONE of those shows up in the folder list in this app. Makes it useful only for looking at new emails. Also, the Files section does not work as expected. It's showing some files, but no clue where they came from, and when I try to connect with OneDrive for Business it tells me that account doesn't exist. Must only work with Personal. Update: two years later and despite upgrades to the app none of my folders of stored mail are still accessible in the app. And now that the OWA app has been discontinued other users in our org are forced to use this app and have the same problem. Needs a fix.
Better than ever, but I’d like a couple changes
mylandmark on 5/22/2018
Overall this is a great iOS app. I mange many Office 365 environments and recommend it to my customers. I would like to be able to see the time an e-mail was sent without having to forward or respond to view the arrival time. I’d also prefer the application not assume I only want to respond to a specific address. Having to click back to edit the recipients is a first world problem worth writing down I guess.
Multiple Issues 🤔
mendozavr on 5/22/2018
1. Neglects important emails: How is someone supposed to focus on an important email if the Focused Inbox feature hides it? 2. Drafts started on desktop Outlook do not appear in the Drafts folder. 3. Slow to launch and slow to update. 4. Can't select a meeting location to find it on a map.
Menu button no longer working
TTTH3 on 5/22/2018
This started yesterday. I cannot selected the menu button to go to my sub folders, tools or to even report this problem under support/trouble. When I select the menu it looks up and I have to close the app and then reopen it to get it to respond. This is only done to get the app to function again. If I try to press the menu button again it freezes and I have to close the app and reopen. I hope this can be fixed. I use my sub folders a lot.
Love it- easy to use.
knaomi14 on 5/22/2018
I’ve used many other email domains. I never thought Outlook would be my favorite. It is super easy to use- I love it!
Love the app. Much better than the basic email app
R-Cardo on 5/21/2018
I love this app. I use app products throughout my house, but have to use a PC for work. That said I absolutely love the Microsoft suite with office 365 and how well it works between the different platforms and especially how I can still access it all though my iPhone. The outlook app is just one of the several tools that make my life easier and time more effective AND efficient.
Worthless Widget
Antsofthesky23 on 5/21/2018
The widget no longer loads the calendar at a glance. It says “unable to load” all the time now.
Best email app for business, and personal
M6iT on 5/21/2018
I have been using this app couple of months after it came out. I simply love everything about it. Easy access to my attachments from within the app. Keep my business email spectated from my personal, Intuitive, fast integrations .... really great. I would want to see a better way to add contacts(email address) directly to my contact list but a small thing when everything else works great.
Logostarz on 5/21/2018
Works well, of course little bugs but they’re fast to come out with patches. Support is awesome! Also, work great with all my other Microsoft applications and o365
Amazing !
Karim-1 on 5/21/2018
Help for everything minute a minute..Thanks!!
Something disastrous happening with zero attention from tech support!
Olgamyself on 5/21/2018
Outlook blocked all my messages ( in- and out- ) as Spam. My account is practically dead , including the Help and Tech Support. Very few incoming emails came in . Mostly rejected by server as SUDDENLY UNRECOGNIZED...
sukh' on 5/21/2018
It’s great. Recommend it for sure.
Message search is useless
John R. Ellis on 5/21/2018
Searching messages is nearly useless. There’s no way to search your Deleted folder or to search by sender or recipient. I’ve reluctantly gone back to iOS Mail app.
App has gone DOWN HILL
JPichinson on 5/21/2018
Typical Microsoft unable to keep their software updates. What a surprise. Strike 1: cant copy and paste easily in the app anymore. Strike 2: Can’t type an email, brings my view to the bottom of the signature right when I start typing, which disables me from reviewing my message as I type. Strike 3: Calendar is not searchable and events do not immediately populate after creating them, makes me nervous if they get into my calendar.
iPhone X Bug
NvTSac on 5/21/2018
Outlook is great but now I’m having an issue with orientation when replying to emails. It cuts off so I can’t see what I’m typing. Please fix :(
Can’t send reply’s to emails on iPhone X
Higgins1211 on 5/21/2018
Pretty useless if I can’t reply to an email. I hit reply and the keyboard pops up. The “return” button is where the send button is. If I hit return it starts a new line. I can’t collapse the keyboard to hit the send button.
Good but could be better
Travis Kennedy on 5/21/2018
Would be awesome if you could let this app access my iPhone address book instead of always having to go back and fourth between the 2
Approve/Reject Capability
GeoBan15 on 5/21/2018
We need the ability to Approve or Reject emails from the Microsoft Exchange Approval Assistant. This has been a long requested feature that has been unavailable on MacOS and with the loss of OWA, now unavailable on iOS without having to log in to a browser every time a request comes in. Please add this as soon as possible. Thank you.
Good but missing features
sramani123 on 5/21/2018
Outlook app performance is good, but, archiving, moving to folders and flagging of emails is not easy which is essential for a mobile email application.
