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?
