Alygatorinthevalley on 2/19/2018
More colors for calendars, initiate read receipt for recipient, undo an email on mobile, have month view on calendar, include more alert options on calendar (I.e. more than a week before the event or allow on a specific day), add a search option for the calendar, etc.
Where is the send button on iPhone 10?
Higgins1211 on 2/19/2018
I write the reply to an email, and the send button does not appear. I have to click return on the keyboard, exit the email, click draft, then it appears. This happened since the last update.
Gets better and better
Jonesy 7 on 2/19/2018
Don’t miss the apple mail client!
Email Search
Steamroller769 on 2/19/2018
Can’t search sent or received folders individually. Have to search a contact and all emails come up, both sent and received.
Outlook works great!
M.B. Enterprises on 2/19/2018
Very reliable! The only thing I hate is that I cannot review events on my personal calendar from work.
Ideal for people moving from windows phone
Sudarsanyes on 2/18/2018
Works like a charm. Loads fast and easy to use user interface. A dedicated app shortcut for calendar would have been awesome.
Amirachan on 2/18/2018
When someone responds to an email the last responds i at the bottom of the thread ... it is so confusing... it should be on top of the thread ....
LuckyOvie on 2/18/2018
Outlook is very good
Love multi-account use
Gleb L. on 2/18/2018
Love that I can use my gmail, work, and school account all in one app!
Support makes up excuses to cover bugs
Paparattzy on 2/18/2018
I regularly jump back and forth between mail apps trying to find the best one that has the features I need. I run my business with my iPhone/iPad and need certain features to be working. Recently, I reported to Support that in the notes section of an event I often put a client’s phone number for future reference. If I need to contact that client, I can hard press the phone number and get a popup menu of options of what to do with the phone number like call, sent a txt message, etc. I reported to support that after pressing one of the options, nothing happens. Support’s reply was that the iPad wasn’t meant to make phone calls and that is why nothing happens. Holy Cow, I couldn’t believe what I was reading. I promptly opened several other email and calendar apps, found a phone number, and was able to do whatever I wanted from the popup menu, including send a txt or make a phone call. Overall, I do like the app but Support personnel’s response to me was an insult if they thought I would accept that answer and go away.
Mad Monk 11 on 2/18/2018
I’m finally getting to where I can use this thing, which I’ve wanted to do for awhile, since I’m into OneDrive. It’s still behind the Apple apps in a number of ways. Concerning the calendars, you can’t create or delete calendars/folders. Setting a location for an event has to be a location in their database. Addresses of your contacts aren’t recognized. When I use the share button in Apple News or Flipboard to e-mail links to people in Outlook, the links don’t work when they click on them in the Mail app on their iPhones. Moving e-mails takes three taps because the move button is in a menu instead of root space. There are some cool features. Focused inbox. Save to OneDrive. Chat-like quick reply option. Great stuff. But certain basics of e-mail aren’t quite there yet.
Mmcgill829 on 2/18/2018
The most recent update requires I ‘login’ to my gmail account every time I open the app. It is endlessly frustrating! Please fix!
Much better than...
Cadiz93 on 2/18/2018
Much better than AppleMail app for iOS. Thanks Microsoft!
It keep freezing
Cashincal on 2/18/2018
It keeps freezing when I try to open any email
Needs to include Outlook tasks
me4wsu on 2/18/2018
Access to tasks should be incorporated into the app. This is nearly as important as email.
Pretty good
Del3660 on 2/18/2018
So far pretty good. Faster than the Apple mail app for multiple accounts. Is there a way to change and adjust the number of preview lines shown in the app?? I don’t want 4 lines of name, subject and then the first part of the message. I would like to have more space. Is this an option I am missing ??
Some bugs
Jargonloster on 2/18/2018
I like it for the most part, and I love the PC version, but for some reason this one doesn’t stay synced with what I do in my computer. Whenever I delete or read mail on my computer and then open the app, it still shows that mail that’s either deleted or already read.
App keeps crashing
meredithutah on 2/17/2018
The app crashes during account setup of my IMAP account. There are only so many times you're willing to retype all of your information, before the iPad makes it across the room.
Tool Box!!!!!
Donnietennis on 2/17/2018
Add tool box!!!!!!!!!!!!!!! It’s like the most important thing you need!!!!!!!!!
Well worth it. Get it.
Guardian_85 on 2/17/2018
Definitely recommend.
Folder notifications and files app support
Nonstationary on 2/17/2018
Need to add integration for files app and notification/sync for custom email folders Also really needs to support iOS files app
Works great
Super hero mama on 2/17/2018
Love the outlook app, I like having a lock on the email for work and it host multiple different accounts that interchange easily.
Works like a charm
sunsoaker96 on 2/17/2018
Works like a charm!
Must Have
beemer5073 on 2/17/2018
Best email client out there, especially for business!
Keep asking me to login to my gmail account
Good Ol Tux on 2/17/2018
Love the app. I’ve had it since forever. It seems with the last release it keeps asking me to login to my gmail or remove the account from outlook. I put my password in and I can send or receive email. Anyone know what is going on? Will 5 stars when that issue is resolved.
Needs another update - gmail not working
JVKing12 on 2/17/2018
Have had outlook on my phone for months now, love it but most recent update keeps kicking me out of my gmail. Please fix, thanks!
Mmmmcha on 2/17/2018
Not sure is going on with the app as I recently updated it and now all I get is a white screen..... I would give it more stars but lately there have been so many issues like scrolling down to find older emails and it doesn’t load whereas I have to try and remember the persons email by typing it in the search bar. Not cool. Especially when it’s an important email. Please fix the issue.
K Sonic on 2/17/2018
Needs “cancel” for login pop-up
Tteddytyuy on 2/17/2018
Outlook needs a “cancel” button for account login pop-up. Sometimes you just don’t need to login this account and it forced you to login before you can read other accounts’ emails.
As usual MS product are not user friendly
zabole on 2/17/2018
As usual MS product are not user friendly. Each time I use any MS product I spend more time to do simple stuff. Unfortunately, they do that so we buy there courses. After learning any product and started to be familiar with it they change the interface and we have to start over again. So bad way to fours people to study there course and certificate. I started to be away from MS products because I’m sure they always wasting my time. That is why no one use there phones because we found companies that respect our time. I have entered my email information but could not access. Instead of google it I switched to another product.
Keep getting duplicate emails
ej_6dunmore on 2/17/2018
I don’t know if it’s outlook’s problems or my schools but I keep getting duplicate emails and it’s been happening for along time and it only happens in the app. Is there a way to remove the duplicate email please let me know!
Good, not great
Vernie T on 2/17/2018
Love, love, love the Focus view! It is awesome at weeding out the important emails from the noise. And the ability to create a calendar event from an email is what I love about Outlook. But that’s evidently only an option if you need to authenticate to remote servers somewhere. No way to add an event to the local calendar on your iPhone. Same with contacts; doesn’t ask for permission to access your contacts and then says you have none. Much less helpful than it could be.
New versions ruined this app for me
Game Design Dr. on 2/17/2018
I used to be a huge fan of this email client. It used to deliver everything that the other ‘advanced’ email clients were doing and the killer feature was the ability to convert a thread into a meeting invitation with just a few clicks. However, the most recent versions ruined some basic functionality that is critical for me: - copy paste using an iPad keyboard is no longer working - Attaching files from dropbox is no longer working - you can only include a link - Searching the mailbox is gone and the new search functionality is not effective for most search scenarios Fix this app please
JLSTexas on 2/17/2018
I do not want an email program that randomly drops your login information and you have to login again. This one does that. I should only have to do it once.
Gafer03 on 2/17/2018
It has been very useful since I installed it. Thanks
Wish it was better but still pretty decent
Ginnydoll08 on 2/17/2018
I love the fact that the email is in the same app as the calendar but I wish the app was better. It always falls short of what I want. But not in major ways. I have multiple emails linked to it and wish I could cross save emails between the accounts (iphone’s app lets you do that). Yesterday the app asked for the password to one of my email accounts. I ended up having to uninstall and reinstall the email account. Today it is asking for another password to a different account and this one won’t take. Even when I uninstalled and and tried to reinstall. (If this doesn’t get fixed, I will have to delete the app and use something else) I hope Microsoft incorporates other calendar options to the calendar section so my iphone calendar can be added and this app can alert me to the birthdays I have saved in my contacts. I also wish the alert times were customizable and offered a second alert or a travel time alert. It would also be nice if it had it’s own contact list to store contact information that I don’t necessarily want saved with my phone contacts. (I don’t like to store contacts within my email accounts.) Overall, I find it the best option for my needs and hope it will only get better in the future.
Bug with Apple Pencil signatures
balderoine on 2/16/2018
I personally love this app but one of my exec users complains about the signatures on pdf documents not displaying in the app. She uses the default mail client to sign documents on her iPad Pro using Apple Pencil but when she opens the sent email in Outlook, it’s completely gone. The default mail client and the browser displays it just fine, just for some reason it disappears on the Outlook app.
IOS Version A+
Jgrandjon on 2/16/2018
Been using the Apple iPad to access all the features of the app, great portable Live version.
Great app
Hjuuikmhgt on 2/16/2018
Great little app love to use it
Outlook is best
jgwick on 2/16/2018
There just isn’t any real comparison. Outlook sets the standard
Great App
GC2007 on 2/16/2018
Great App
Outlook vs Gmail
bucsstophere on 2/16/2018
Much easier to navigate and organize!
JessiC1990 on 2/16/2018
I had this app on Android and wound up uninstalling it because I wasn’t getting emails. So now I am trying it on iOS and hoping that it will be reliable. Based on the reviews, I think it will work out. What I love about this app is that you can add your TV shows from the Interesting Calendars setting and their showtimes show up on the calendar. It seems you can also add sports as well and connect some other apps you might use as Add Ins for your Microsoft email account.
Outlook Mobile application
Ummtamim on 2/16/2018
A good application with 2 thins remaining; 1- ALIAS Field, while searching for a contact, or display contact priorities. 2- Search in Folder, Subject, TO, etc.
Easy to delete emails
Krspyleg on 2/16/2018
I’m converting all my mail here because I can go through and pick out the ones that matter and mass delete the rest. The delete is the best feature
Outlook calendars
kestrel99 on 2/16/2018
It would be good if you could pull up a month view of the calendar on a hand held device like a phone. Maybe you can and I am missing it, but I often need to see dates further into the future. Thanks!
Nice app but...
Art H. on 2/16/2018
Wish it had more ways to filter other than focused and other. But the app is very useful
Outlook Update
EM DC on 2/16/2018
Very disappointing update. The contacts tab was one of the main features that was extremely useful to me but now is no longer available. Why have multiple apps do the job of one. The interface and order of emails chains is confusing and not well organized.
