can't accept a teams meeting invite from outlook

Dear @Ken Olson,

To ensure I understand your request correctly and to support you as effectively as possible, I need more specific information from you:

Could you share a screenshot of the issue?

Is this issue happened recently?

Are you using a personal or business/ school account?

Which version of Outlook (New Outlook, Classic Outlook, OWA), and Teams (Teams app, Teams web) are you using?

Are you unable to accept all Teams meeting invites, or only specific ones?

Are other users experiencing the same issue, or only you?

Could you confirm if Teams and Outlook are using the same account?

The information you provide will help me assist you more promptly and efficiently.

In the meantime, kindly check if you could accept the meeting directly from the Teams app > Calendar
