Teams status does not reflect availability

Thomsch 

If you have items in your Outlook calendar they should carry over to Microsoft Teams calendar.  From what you are saying, you are seeing those items in the Microsoft Teams calendar.  In that case, your presence in Microsoft Teams should mirror your Outlook presence.  If you have a meeting at 9:00 a.m. that was scheduled in your Outlook calendar, it should show you as busy at 9:00 a.m. in Teams.

This doesn't sound right.  Please select the question mark icon on at the bottom left hand side of your client and report the issue to our team.  Here's some more information on how presence works: https://docs.microsoft.com/en-us/microsoftteams/presence-admins

Thanks for reaching out.
