Controlling settings, permissions, and membership within Teams and channels
Since the Teams admin center action produces no response, add the owner with the supported Teams PowerShell cmdlet Add-TeamUser.
Add the owner through PowerShell
- In Teams admin center → Teams → Manage teams, enable the GroupID column through Edit columns, then copy the affected team’s GroupID. The GroupID identifies the Microsoft 365 group backing the team.^1^
- Open PowerShell and run:
Install-Module MicrosoftTeams -Scope CurrentUser
Connect-MicrosoftTeams
Add-TeamUser -GroupId "<team-group-id>" `
-User "[Email]" -Role Owner
Replace:
-
<team-group-id>with the copied GroupID. -
[Email]with the user’s organizational user principal name (UPN).
Add-TeamUser adds the account as both an owner and a member of the team’s backing group. The command returns immediately, but Microsoft notes that the Teams client can take 24–48 hours to display the change.^2^
- After the command succeeds, check Teams admin center → Teams → Manage teams → team name → Members. The account should appear with the Owner role.
If PowerShell reports an authorization error
The account performing the change needs an administrative role capable of managing Teams, such as Teams Administrator or Global Administrator. A Teams Reader role is read-only and cannot make this change. Microsoft recommends using the least-privileged suitable role rather than Global Administrator.^3^
After the appropriate role is assigned, reconnect so that PowerShell obtains a new authenticated session:
Disconnect-MicrosoftTeams
Connect-MicrosoftTeams
Add-TeamUser -GroupId "<team-group-id>" `
-User "[Email]" -Role Owner
Alternative administrative path
If Teams PowerShell also fails, manage the backing Microsoft 365 group directly:
- Open Microsoft 365 admin center → Teams & groups → Active teams and groups.
- Select the group corresponding to the team.
- Open Membership → Owners.
- Select Add owners, choose the member, and then select Save and Close.^4^
This alternative is relevant because a team created from an existing Microsoft 365 group inherits that group’s permissions.^5^
If both administrative methods return errors, capture the PowerShell error text and the team’s status from Teams → Manage teams; those details are needed to distinguish a permissions failure from a problem with the team or backing group.
