Outlook not working at all on iPad after update to V 5.2602.0

Question

Outlook not working at all on iPad after update to V 5.2602.0

Trevor Fayers 330

My IPad (iPadOS 26.2) updated Outlook to Version 5.2602.0 this morning, Since then, I can open Outlook, but nothing works at all. It seems to be able to update the mailboxes, but nothing happens when I click on anything. This needs an urgent fix. Are others experiencing the same issue please?

Yes but in my company we have about 500 ipad devices and none of the devices can use the outlook. When i remove the app install again we can use just one time. When i close app and open again same error occurs.

I have also just sent feedback to MS using my Android Outlook app. If others are able to do that, it might help to get the issue addressed. Thank you

The workaround I found is using the Safari browser instead of the app. The app will still send you notifications.

Thank you Malcolm. I tried that, but it didn't work for me. There was a very temporary return to full functionality, as there has been throughout the day anyway. But after I try to do anything in the app or close and reopen it, the issue returns.

Could this issue be linked to MS' new Intune Management policy - search 'Mandatory Intune MAM Security Update (January 2026)'. Seems rather a coincidence that the policy was introduced on 19 January and this issue occurs with the first MS Outlook for iOS after that.

I shutdown and restarted my iPad. I deleted the app and did a reload fresh. Same result. Last update broke the app. Urgently need an update app is completely unusable. This is existing on my iPad only… phone and desktop versions are ok.

Same issue all day, a work around I found - press hold Outlook app icon, tap calendar, once in calendar I press mail button….. a pain, but better than deleting and reinstalling app and network settings…..

Hey Jarrod,

cool - your workaround works on my end as well. Would have never ever thought on this option. So let‘s have MS to fix it ASAP.

May have discovered a more permanent solution, and the source of the problem. Need to do more testing, but after getting into the app through the calendar and selecting an email, I noticed a little "new" label on three dots along the bottom. I selected that, got a popup saying email actions had moved, and after clearing that and closing email actions the app no longer freezes when closing and reopening the app like it did.

Like I said, I need to test it on a few more iPads, but that popup may be the root cause.

Edit: Nevermind, it seems I got ahead of myself.
