Team Missing From Teams Admin Center
Cause:
An attribute on the underlying modern group isn't correctly populated.
Replace {groupid} in the Query for the actual GroupId in question, which you can get via the Exchange Online powershell, with the "Get-UnifiedGroup" cmdlet, as the "ExternalDirectoryObjectId" attribute or by looking the group up within Entra.
1. Access Graph Explorer
2. Sign in to Graph Explorer on the top right-hand side menu:
3. Change the query line to: PATCH > v1.0 > https://graph.microsoft.com/v1.0/groups/{groupid}
4. Click the Modify Permissions tab and consent to any permissions required (you do not need to consent for the whole organization).
5. Add the following value on the request body: {"resourceProvisioningOptions": ["Team"]}
6. Confirm you receive a 204 response in the middle of the page.
7. Confirm the team appears correctly back on the Skype & Teams Admin Center - Team Overview.
