Hi Bob. Thank you for coming to the forum. My name is Femi. It is worth noting that this is a user community, and we are all users here, much like yourself. While we strive to assist and share insights, we are not Microsoft directly.
I understand you are unable to leave an organization despite asking the Admin to remove you. I understand how frustrating that can be. Rest assured I will try to provide you with a solution.
We’ll need more details regarding your issue to assist you more efficiently. Below are some questions that may help us isolate the issue you are experiencing.
Are you using the web browser to access Teams or the app?
What device are you using currently?
Did you try to clear Teams Cache before attempting your exit?
Regards
Femi
