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.

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).

 

 

4. Add the following value on the request body: {​"resourceProvisioningOptions": ["Team"]}​

 

5. Confirm you receive a 204 response in the middle of the page.

 

6. Confirm the team appears correctly back on the Skype & Teams Admin Center - Team Overview.

Note:
If the steps fail with a 403 and all permissions are correctly setup, please verify if the group is assignable to role, which will be expectedly failing.
