As a Teams Administrator, it's crucial to know which Teams groups are inactive. This helps you clean up these groups when needed. This article will show you how to find inactive Teams using the Microsoft 365 Admin Center and CoreView.
By checking the “Last activity date” column, you can determine if a Teams group is inactive (for example, if the last activity date was more than six months ago) and take the necessary action.
You can also perform various actions directly from the report page in CoreView. For example, if you want to delete or archive any inactive Teams group, you can do this straight from the report page. Simply select the group and choose “Remove Teams group” or “Archive Teams group” from the “Manage” tab options.
