Update-MgUser fails to remove OfficeLocation value

[VonGlitch]

I am using Update-MgUser to update OfficeLocation values and sometimes when a person is between locations, or not yet assigned a location, we want the location field to be empty. But if I pass either an empty string or $nul the cmdlet fails. How do I remove the OfficeLocation value. We don't want to populate it with garbage!

PS C:\admin\365\SharePoint> Update-MgUser -UserId $User.Id -OfficeLocation ""
Update-MgUser : Invalid value specified for property 'officeLocation' of resource 'User'.
At line:1 char:1
+ Update-MgUser -UserId $User.Id -OfficeLocation ""

Thanks for following up on this.

The SDK does not currently support setting properties to null due to a design limitation with the code generator - Azure/autorest.powershell#961.

As a workaround, please use the Invoke-GraphRequest to set properties to null as shown below:

Invoke-MgGraphRequest -Uri "v1.0/users/$userId" -Method PATCH -Body @{ OfficeLocation = $null }
