Issue assigning phone number to new user MS Teams Powershell : Set-CsPhoneNumberAssignment

Question

I am writing a script to automate the creation of resource accounts in MS Teams using PowerShell and by retrieving infos from Excel file. After creating resource accounts and assigning licenses, i am trying to assign a phone number with the command

Set-CsPhoneNumberAssignment -Identity "upn" -PhoneNumber "+33..." -PhoneNumberType CallingPlan

but I get the same error everytime :

Microsoft.Teams.ConfigAPI.Cmdlets.internal\Set-CsPhoneNumberAssignment : The server responded with a Request Error, Status: NotFound

I seached on google and found that it might be a MS issue, did someone already encounter the same problem?

Thanks !

Answer 1

You might want to update your MicrosoftTeams module to 4.3.0 (current non-preview) release, restart your PowerShell session and retry. They made some fixes to that cmdlet in that release.
