Invite disappeared from Outlook - Can't reschedule the meeting with 50+ participants

Copper Contributor

Hi all,


I have a user who has scheduled a meeting, with about 50 people.

It has now disappeared from his calendar. Outlook and OWA.

If people update the meeting with for example a different time, he gets the email. The invite does not show in the calendar.

He can not cancel it either, as he does not have it anywhere.


Please advise

Hi @Ion-vlad Orascu 


Check Deleted Items Folder. Check if the missing meeting is in the Deleted Items folder.

Rules and Auto-Decline. The user should check for Outlook rules that declines or moves meetings.

Since the issue affects Outlook on the Web (OWA), another test should be done. Check if the meeting appears in OWA after accepting it there. 

Also check Shared Folder Caching. In Outlook, click on File > Account Settings > Account Settings.

  • Select your account and click on Change.
  • Then, click on More Settings and navigate to Advanced.

Are other users affected or it's just this specific user?
