Additional meeting and call-related features and issues within Microsoft Teams for business
Do you have two accounts? Are you scheduling your meetings through the Outlook add-in? If the answer is yes to either question, then that may be the problem. I originated the question in the forum some time ago, and at least for my purposes I no longer have this issue. I have made a significant change in how I create my meetings. My suggestion is: Do not use Outlook to create meetings. I have had no difficulty since I started creating the meetings in the Teams app instead of in Outlook. Hope that helps.
