Meetings disappear from calendar

Hello! When I schedule meetings in Teams, they first appear in my calendar, but literally after a minute, if I change the calendar window, they disappear, although the people I invite to the meeting ...

Kirill_ProninI believe some, but not all, of my users are experiencing a similar issue.

 

A commonality I've observed for the sequence of events that can lead to disappearing calendar invites:

  • Friday - Meeting organizer drafts an invite in Outlook Calendar.
  • Friday - Meeting organizer converts Outlook Calendar invite to a teams meeting.
  • Friday - Meeting organizer sends invite.
  • Friday Night - Meeting attendee accepts meeting invite on I-phone via Mail App and sends Acceptance e-mail/notice to Organizer.
  • Monday - Meeting organizer sends out update to meeting invite (not a time change just a text update with an agenda)
  • Monday Night - Meeting attendee comments that the meeting is not appearing on their Teams Calendar in Teams on Windows 10 (or Outlook calendar in Windows 10)

We are 100% Office 365 users.

 

My best guess at the moment:  Something about a user on a mixed OS environment Exchange sync setup is causing issues.

 

I've gotten hints of concern from users enough now that I'm beyond "must have been a goof" and believe something is going wrong.

 

Anyone else?

    I also experienced the described behaviour. I could track it down to having an email forwarding configured for the user. If forwarding of emails is disabled everything works as expected. Does anyone have an idea whether and how this could be related?

    We've been seeing this a lot this week.  We run a mixture of iPads and Windows clients for creating meetings.  Pupils are accepting them and they're vanishing.  They're only using one device as I at first thought it might be being signed into a phone, laptop and iPad for example.  We also now have the problem that staff have updated meetings but can't delete the old ones because they don't show.  The pupils can see them still though and join the wrong one.


    Did anyone ever get to the bottom of it?
