Additional meeting and call-related features and issues within Microsoft Teams for business
To better understand your situation, could you please clarify a few details?
- Were the meetings originally created by you, or were they organized by another user?
- Are you looking for meetings that no longer appear in your calendar, or are you trying to find meeting recordings, transcripts, or other meeting-related content?
- Does this affect all past meetings or only specific ones?
If you are referring to meetings that no longer appear in your calendar, please note that if the meeting organizer deletes or cancels the meeting, it may no longer be visible from the attendees' calendars.
It may also be worth checking with your Microsoft 365 administrator to determine whether any retention or messaging records management policies are configured in your organization that could automatically remove calendar items after a certain period.
Your administrator can review the following Microsoft articles:
- Default folders that support Retention Policy Tags in Exchange Online View article
- Configure Microsoft 365 retention settings to automatically retain or delete content View article
Once you can confirm whether you're referring to calendar entries or meeting recordings/transcripts, and whether you were the organizer or an attendee, I can help narrow down the possible causes.
Thank you for your patience and understanding. I hope this information will be useful to you.
