Issue just started this evening. When I open the IOS Outlook app, it will crash and close after a few seconds.

@Jade Ng how are we supposed to report the issue through the Outlook for iOS if the app crashes immediately upon opening and we cannot access support?
I am running iOS27 on an Apple 16 Pro Max and Outlook app version 5.2637.0 and the app crashes immediately unless opened in Airplane mode. All iOS and app versions are latest revision. App continues to crash after multiple device reboots.

Same issue here. I am running iOS27 on an Apple 15 Max and Outlook app version 5.2637.0 and the app crashes immediately unless opened in Airplane mode. All iOS and app versions are latest revision. App continues to crash after multiple device reboots. Even setup user on a new phone and Outlook continues to crash for the user. Seems to be an issue with 5.2637.0. My personal phone has outlook app version 5.26.35.1 and its running fine with no issues.

@Jade Ng this is still unresolved. Please provide an expeditious update. I am using enterprise apps and rely on Exchange for business-critical applications and Outlook for iOS continues to crash.
Both iOS and the app have been updated to the latest versions.
I can provide iPhone crash logs if needed.

My IT department is clueless on how to help me fix this issue. I cannot do anything with my phone for work. I have a. iPhone 15 running 26.7 and Outlook version 5.2637
Dear Everyone,
For the time being, please use Outlook on the web as a temporary workaround to access your email and calendar where possible.
I will continue to follow the status of this issue and will update this thread when a confirmed fix or further information becomes available.
Just FYI - I'm seeing a report on Reddit that this was fixed with version 5.2637.1 from the App store. I can't confirm.
[External Non-Microsoft Site] https://www.reddit.com/r/Outlook/comments/1wnl29o/iphone_app_crashes_on_launch_help/
u/pegboy4691 - a new version of the Outlook app for iOS is now avaiable in the app store. 5.2637.1. We just tested with 3 users and all 3 users are no longer crashing

Latest version installed, still does it. Weirdly it only one 365 account causing it, if I don't add that account its fine.

You obviously are not seeing the same problem as most others. You need to start a new thread using the "Ask a question" button at the top of this page to create a new Question and include the details for your specific problem.
Dear Everyone,
For anyone still experiencing this issue, please refer to the latest update from the original poster. They confirmed that they updated the Outlook app and are no longer experiencing the crashing issue.
Please ensure that your Outlook for iOS app is fully updated and then test again to see whether the issue is resolved on your device.
Update fixed it for my phone. Thank you

Mine is doing the same. Latest version of IOS and latest outlook iOS version.
i have 3 accounts on my outlook app, if I remove my personal account. The app works. But if I have my 2 work accounts and my personal account: the app closes. All are Microsoft accounts, if I have 3 accounts and have aeroplane mode on the app won’t close.
this needs to be fixed ASAP,

Just FYI - A possible workaround from a previous Outlook for iOS issue that some Reddit users are saying also might help with the current problem. (Just hearsay. I don't have the bug and can't test).

I'm having the same issue as Dan Nesbit. Latest versions of iOS and Outlook installed. Works fine with one account but crashes when multiple Microsoft email accounts added. help! I need to monitor multiple emails at once.
Hi,
I understand how important it is for you to monitor multiple email accounts at the same time.
Please review the workaround shared by Hornblower409 in the comment above and see whether it helps in your case.
Those work arounds do not work for me. I'm on latest version of both apps Outlook 5.2638.0 and iOS 27.0.1
Still having the issue with multiple Microsoft accounts . Works fine when only have one account added but crashes when multiple accounts added
Dear Oeftering, Matthew P,
Based on the symptoms you described, this may be related to a currently known issue affecting Outlook for iOS version 5.2635.1 on older versions of iOS. Microsoft Engineering is currently investigating this behavior, where Outlook may become unresponsive during startup or crash when launched.
For reference, please see: Outlook for iOS may become unresponsive or crash on launch
While the issue is being investigated, Microsoft recommends the following workaround:
Thanks for your patience and understanding so far. Hope you having a nice day and really much warm regards to you as well!
I’m currently running iOS 27 and the symptoms are still there.
Dear Oeftering, Matthew P,
Thank you for your update!
Since the issue persists even after updating iOS, please try the following steps:
If the issue still occurs after these steps, it may be related to the Outlook for iOS issue that Microsoft is currently investigating. In that case, please continue using an alternative method to access your mailbox where possible (e.g. Outlook web) while Microsoft works on the issue.
I would also recommend reporting the issue through Outlook for iOS so that the Outlook team can receive additional diagnostic information from affected users.
Thank you for your kindness and understanding.
Dear Oeftering, Matthew P,
I hope you are doing well!
Could you kindly confirm if there have been any recent updates on your side?
Thank you for your cooperation. Looking forward to hearing from you!
Still unresolved. 5.2637.0 and iOS27
I travel for work. This is becoming unacceptable that I can’t access Outlook to manage emails and my calendar without painful workarounds.
Dear Oeftering, Matthew P,
I’m sorry the issue is still occurring, and I understand how frustrating this must be, especially when you rely on Outlook while travelling for work.
The issue is currently being investigated by the Microsoft product team. In the meantime, please use Outlook on the web as a temporary workaround to access your email and calendar.
I will continue to monitor the issue, and once a fix is confirmed, I will update you here as soon as possible.
Thank you for your continued patience and understanding. I sincerely apologize for the inconvenience this has caused.
I’ve updated the app and no longer having the issues.
Dear Oeftering, Matthew P,
That’s great news! I’m glad to hear that after updating the Outlook app, the crashing issue has been resolved and everything is working normally again.
If you encounter any other issues, please feel free to post a new question so other moderators can help, or tag me so I can continue supporting you in the future.
Thank you very much for your valuable time and your cooperation.
