Searching email has the worst experience
Srichakram on 7/19/2018
Searching emails on the app is a terrible experience
Highly recommend it!
Raj1418 on 7/19/2018
Hey great app! I would love to see calendar improvements and the ability to schedule drafted emails Keep up the great work!!!
Annotation not saved frequently
silei.xu on 7/19/2018
I use this to organize and annotate pdf files. But very frequently, the annotation is not saved after I close the file. It happens more often when I work on one file for a long time. Very annoying.
Users who need help on 7/19/2018
Need to be able to silence the Alerts please. Thanks.
Too complicated
Wolf_Major on 7/19/2018
I’m unable to delete old accounts I don’t use any more and new accounts won’t show after signing in on the app.
Update broken
NicholasCheck on 7/19/2018
Last update is really buggy - please fix. Photo attachments are breaking app, mail doesn’t appear to be sending.
Best in the Business
Thought Passion Action on 7/19/2018
Email clients come and go but Outlook has always been secure, stable, and surprisingly efficient and effective.
iPhone and Outlook
I'm a fan Bible on 7/19/2018
I love being able to check my email from my iPhone and outlook makes it easy.
Keeps freezing
dennyIT on 7/19/2018
This app worked great for about a year, now it’s not doing the job anymore. I use it for work so it’s not like I can actually simply stop using it. Lately it hasn’t been sending out email, freezes as I type, freezes just in general as I’m trying to get the job done. It’s not responsive to any kind of command or touch anymore. What happened??
Too many bugs
Adam9408 on 7/19/2018
I ditched Gmail for this and I’m regretting it. This app has so many bugs and glitches it barely functions. My emails don’t send, I don’t receive half of my incoming mail, and attachments don’t ever work. Microsoft should be embarrassed!
Outlook App replaces email Native iOS app
swhitelexington on 7/19/2018
The outlook app does replace the Native iOS app. there is one item if I could have is sending a delay email. that would complete the process. No issues with syncing calendars and emails correctly as it’s a pain with the native iOS calendar and phone and iCloud. It keeps things very nice and tidy.
Reporter_Pete on 7/19/2018
The interface is a bit complex but doable.
Slow load
vacationanthony on 7/19/2018
Recent update has significant performance issues. Crashing immediately or everything screen freezes while it loads.
Loved the app until...
Esq__ on 7/19/2018
I use this app for my work email. There is no delay in receiving messages and the Outlook calendar syncs well with iCloud calendar. I am now having an issue with the search function. It simply does not work, which is frustrating.
Некачественное приложение
+555 on 7/19/2018
При обновлении списка писем постоянно вылетает. Не запоминает пароль от Exchange, приходится каждый раз вводить заново. Работает медленно.
Selecting and Copying Breaks the App with the new iOS Update
applesucksapplesucksapplesucks on 7/18/2018
When you select text to copy the app freezes and is unresponsive.
A ton of lock ups on my iPhone X as of late
Treman99dd on 7/18/2018
The app has become barely functional. I cannot even contact support. The app just locks up while trying to navigate to support. There seems to be a massive memory / CPU utilization issue. I used to rely on this app, but it’s completely broken since the latest update. Closing, and restarting it does nothing. Restarting the phone does nothing. Please fix!
Absolutely love it.
Akshay.Gandhi on 7/18/2018
All the features and options are up to the mark and perfectly useful.
Freezes and crashes
Venkatrj on 7/18/2018
Every few months, the release on this app becomes completely unusable. Not even sure how this even passes basic quality tests. With the latest release, the app freezes on launch and crashes most of the time. Need to wait several seconds for the app to become responsive and do anything useful. Fix it please!
App no longer works
GMAT student1.1 on 7/18/2018
Since latest update, app doesn't load and consistently crashes.
Not working like it once was
William2727 on 7/18/2018
Emails are not being sent when hit send. Then like and hour later I see them as drafts. Very aggravating. I’ve been using this for work but I can’t trust this anymore
bvesco on 7/18/2018
It does exactly what it is supposed to do (email+calendar) without trying to be cute. It’s exactly what I want.
DO NOT download this app
AlphaNYC on 7/18/2018
If you login to one of your outlook accounts such as Hotmail you will not be able to log out. How annoying, and intrusive is that? Microsoft has the attitude if you use this app it owns your iPhone. Microsoft still thinks it is the only email developer out there.
mdyson on 7/18/2018
Whatever happened in the most recent update made this app completely unusable for me. Everything love extremely slow to the point where I can’t get anything done in the app and if I tap something it will just lock up for several seconds. If I dare tap it again it will just push several views of the same message on top of each other one.
Over all Ok
RCDRose on 7/18/2018
Need to be able to see an entire month on the screen instead a week at a time. Difficult to find a date.
Needs to sync Drafts with Outlook on PC
engry player on 7/18/2018
Sometimes i start creating an email on my phone and need to alter it later from my pc or vice versa. Would be very nice if the draft emails would sync as well Thank
Slow load
Originalfatkid on 7/18/2018
This app has slowed down considerably in the last two weeks. What’s up MS?
Sent mail no longer shows in thread.
JynxRD on 7/18/2018
For the past few weeks maybe, not sure how long entirely but now when you reply to an email it no longer shows in the thread if the message. If you were to go back into that email you’d have no idea you had previously replied to it without having to go into your sent mail folder to look for it.
Great except for one significant detail
Joethewest on 7/18/2018
Please set the default to Reply instead of Reply All or give us the option to choose. I am constantly inundated with reply all’s from all over my organization!
Pretty good but look before you leap
Petie Ravioli on 7/18/2018
If you update this app from an older version, it wipes out any locally stored data (such as email drafts and sent items). Be sure to archive anything important to you before allowing it to version up. Since the old version would no longer send / receive ("outlook is out of date, please upgrade" it would say - or words to that effect), and I couldn't simply send drafts to myself for later recovery, I just copied and pasted to Notepad. Not great, but it works. The upgrade experience would be far better if it would simply not have this issue. The other thing I'd like (if any developers are reading this) is a permanent setting for "always bcc myself". Those are my two major observations. Everything else has been fine. Follow up: A couple of years in, and it's still going okay, but not perfect. My upgrade caveats and wishes above for user improvements still stand.
Great for checking emails from work
Marx2cool on 7/18/2018
I’m at a point in my career, in which I’m always on the go, at meetings, at construction sites, etc. This app is great for checking office emails while on the go.
Was great!
Morel1 on 7/18/2018
Used it as primary email & calendar app until yesterday. Doesn’t work at all. Avoid until fixed.
Not able to customize Look and feel
Madhusea on 7/18/2018
Not able to customize look and feel with themes and seeing is big missing feature in this app Other feature good to have is, All the emails in one view , currently mails are routed to different folders based on rules ,this option is good in desktop, clicking on each folder to see different emails is pain on mobile , if there is option to see all emails in all folders would be Nice , nine for Android has this feature
Latest update 7.17.18 iOS
cjklime on 7/18/2018
Since the latest update my ap I freezes when opening up emails.
Attachments disappear after reply!
laserbrian on 7/18/2018
I have at least 1 user that when he replies to an email that has an attachment (iPhone Outlook app), that attachment disappears from the original message. The attachment is gone in the iPhone Outlook app, the 365 Outlook app in Windows, and Everything is up to date on all platforms. We do not use focused inboxes or conversations. The is a huge problem!!! What can be done to resolve?
adedd66754566433 on 7/18/2018
Sometimes when replying to email the box where you are typing does not allow you to see what it is you are typing.
I love it
controls inspector on 7/18/2018
I’m speechless about how much I like it. Oh and by the way I thank you Microsoft for putting an “other” inbox where you can automatically put all emails from a specific sender/contact to that inbox that REALLY REALLYx9999 helped me
App update
The Danglebeast on 7/18/2018
App no longer functions after most recent update.. continuously crashes and huge lag time when trying to open an email. Was great before the update. Please fix!!!
Broken several updates ago
PinkiesOutNYC on 7/18/2018
As others have called out.Slow initial load screen (white). Takes up to 10 seconds to load in. iPhone 8 Plus. Please fix. Update: load issue fixed.
Kurt 26.2 on 7/18/2018
App was great until this update. Please fix!
Latest update unusable
Velhetica on 7/18/2018
The app just hangs, can’t tap on anything, wont load emails. Basically it’s unusable now
Great App for email!
Rocket7771971 on 7/18/2018
Great app to read & respond to email on the go! One improvement needed would be an easier way to move emails into folders like you can on your desktop. Overall great app!
The search tool is awful
Energy huif on 7/18/2018
This app never searches all of my emails. Typing in keywords barely helps.
Add task management please!
drrmsmith on 7/18/2018
Great app. As soon as they add task management it will be five stars!
It keeps freezing on me
hoyoscami on 7/18/2018
This app freezes all the time
Unread Folder
Matt_Stein on 7/18/2018
Want to have unread folder same as on Outlook desktop version
Needs to be able to have information synchronized automatically
JDevereaux on 7/18/2018
There needs to be a interval time period set to ensure the iwatch Outlook app is up to date when you click on the screen. It seems to miss the entire day of events.
Slow and unreliable
applecustomer1234xyz on 7/17/2018
It is so bad I avoid using
Avoid 2.86.0!
Dennis vd H on 7/17/2018
Seems to crash on multiple iOS phones making it completely unusable at this stage
Still broken!
Aberry622 on 7/17/2018
Latest update did not fix anything... Will not sync emails for the last 3 days... Wonderful app when it works, please fix it!
