I have found that after selecting the calendar entry and then rotating my phone, so that Outlook appears in landscape mode, gets the edit option back. I can then rotate the phone back to portrate and edit or delete the entry.
Outlook Mobile impossible to modify calendar events

Hi All,
Since a couple of days, Outlook mobile ( 4.2537.1 ) is not offering anymore the capability to modify events in any calendar. it's possible to create BUT not to modify nor to delete !
Thanks in advance for your support

Keith Thompson 25 Reputation points2025-10-09T23:34:30.52+00:00 Microsofts suggestions to uninstall and reinstall or reset the app is insulting. Multiple people have this issue and it can be reproduced every time. It's a problem with the latest update to the app, just admit it and say it will be fixed in the next update.

Julia Noakes 15 Reputation points2025-10-12T21:25:15.9666667+00:00 Vikki-T, this issue does appear to be a conflict between MS and a recent Android update. I have also performed the steps outlined within this thread, without success. Software is up to date. One UI Version: 8.0 Android version 16 Current Version: S901BXXUIGY17/S901BOXMIGYI7/S901BXXUIGY17 Security Patch Level: 1 September 2025
This has been an issue for approximately 2 weeks. When should we expect a fix for this ongoing fault?

Elaine McMillan 5 Reputation points2025-10-05T23:56:00.63+00:00 It is truly a huge nuisance, resulting in huge loss of time. Please fix the problem as soon as you possibly can. I need to put my events in landscape, then bring it back to portrait to be able to edit or delete the calendar event.

Conwell, Patrick S 25 Reputation points2025-10-08T02:20:08.81+00:00 I can confirm that rotating the phone to landscape and back "fixes" the issue. Obviously, this is not a real solution, but it at least lets you make edits.

Mark Charlton 10 Reputation points2025-10-03T16:10:49.77+00:00 I've also discovered that if you have the outlook home screen widget in use, clicking on an event through there gives you the edit option, when opening the same event via the app, and in the calendar view does not.

David Gibson 0 Reputation points2025-10-22T11:47:53.2433333+00:00 I'd found this worked sometimes. But not always, even for the same appointment. Rotating the phone (and back again if needed) has a higher success rate, but still not 100%.

Hani-N 4,220 Reputation points Microsoft External Staff Moderator2025-10-01T15:41:19.4666667+00:00 Hi @Jean-paul Lanfrey-Denechere
Thank you for posting your question in the Microsoft Q&A forum.
It appears you're currently unable to modify or delete calendar events in Outlook Mobile (version 4.2537.1), though creating new events still works.
To help us investigate further, could you please clarify the following:
- Are the events you're trying to modify in your personal Outlook calendar, a shared calendar, or one linked to a third-party service (e.g., Google, iCloud)?
- Are you using a personal Microsoft account (e.g., @outlook.com, @hotmail.com), or an account provided by your organization (e.g., @yourcompany.com)?
- Is your account managed by an organization or IT admin?
- Do you receive any error messages when attempting to edit or delete events? If so, could you share a screenshot or the exact wording?
- Have there been any recent updates to the app or your device that might coincide with the issue?
- If this involves a shared calendar, do you have full edit permissions?
Once we have this information, we’ll be better equipped to pinpoint the cause and suggest a solution.
Looking forward to your reply,
Warm regards,-

2025-10-01T15:53:04.19+00:00 Hello,
First, thanks the your swift answer!
Then, to your points :
"Are the events you're trying to modify in your personal Outlook calendar"
- impossible to modify on personal or shared calendars
"Are you using a personal Microsoft account (e.g., @outlook.com,"
- personal account 'outlook.com'
"Is your account managed by an organization or IT admin? "
- No
"Do you receive any error messages when attempting to edit or delete events? If so, could you share a screenshot or the exact wording?"
- Unfortunately not... i can only see that the option 'modify' in not present when i open an event.
"Have there been any recent updates to the app or your device that might coincide with the issue? "
- This was coming just after an Outlook update on my android.
Hope this help for the troubleshooting.
Best Regards,
-
