New-CsApplicationAccessPolicy issue

Question

Hello,

I'm trying to add New-CsApplicationAccessPolicy (Team Admin) via PS and i receive error:

New-CsApplicationAccessPolicy: Unable to cast object of type 'System.Management.Automation.PSListModifier' to type 'System.String'.

I used command from docs example:
New-CsApplicationAccessPolicy -Identity "Global MS Teams Policy" -AppIds "000000-00000-xxxx" -Description "Azure is amazing "

Any idea what else i can check?

Hi there,

This might help you out.

• Upgrade the Microsoft team's PowerShell module to the latest .
• Connect-MicrosoftTeams #Enter global Administrator account credential and make sure that you see Admin account details in connection output.
• Now execute the New-CsApplicationAccessPolicy
• Make sure the PowerShell connects/works.
