Orphaned Team is displayed in MS Teams
Hallo, I have a similar problem, as is described at Unable to Remove a (orphaned ?) Team from user interface I'm creating the Team from Outlook (Email -> Group -> New Group), ewerything OK. And then I decided to delete this Team, by deleting the Group / SharePoint / Team. So I've deleted the Group (through AAD Portal), then the SharePoint Site. I've permanently deleted the Group so as the SharePoint Site. The SharePoint Site I had to delete through Powershell, through GUI it was unable. And Yes, by creating / deleting, I was a little quick, I've booted the deletion quite fast after creation (maybe 5-10 min) I was expecting that this team will disappear from Teams Application by itself, but not... But now it's been several days and I'm stucked because the Team still exists, with General Chanel, to which I can add posts (cannot add new Chanel, not Documents, not Users), but I can't remove this Team from the user interface as I'm no more Owner of it, just Member. And of course, I can't see the Team through the admin interface, even from Powershell. I've been looking everywhere, GUI Central Administration, Teams, AAD, Exchange, through Powershell this same ewerywhere, but he is nowhere to see. Through link "Get team link" I got the Group GUID, then I tried to assign me as owner for this Team with the Idea first Owner, then delete, using PowerShell Add-TeamUser -GroupId "GUID" -User user@domain.com -Role Owner. Error: -------------------------- Add-TeamUser : Error occurred while executing Add-TeamUser Code: Request_ResourceNotFound Message: Resource 'GUID' does not exist or one of its queried reference-property objects are not present . InnerError: RequestId: ID DateTimeStamp: 2019-12-20T08:26:40 HttpStatusCode: Request_ResourceNotFound At line:1 char:1 + Add-TeamUser -GroupId GUID -User user ... + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : NotSpecified: (:) [Add-TeamUser], ApiException + FullyQualifiedErrorId : Microsoft.TeamsCmdlets.PowerShell.Custom.ErrorHandling.ApiException,Microsoft.TeamsCmdlets.PowerShell.Cus tom.AddTeamUser -------------------------- Any idea how to remove it? I've got all the admin rights, so no limit on a working solution. Thanks for Help
