[Support Setting Fields to null] Unable to set BusinessPhones or MobilePhone fields to $null

[haneef95]

Hi,

When trying to set BusinessPhones or MobilePhone values to $null, like so:
Update-MgUser -UserId $MgUser.UserPrincipalName -MobilePhone $null -BusinessPhones $null

It throws an error:
Update-MgUser_UpdateExpanded: Invalid value specified for property 'mobilePhone' of resource 'User'.

I've fixed this for now by using an alternative command:
Invoke-GraphRequest -Method PATCH -Uri "https://graph.microsoft.com/v1.0/Users/$($MgUser.UserPrincipalName)" -Body '{"businessPhones": [],"mobilePhone": null}'

Hope this helps someone else in a similar need and more so, the Update-MgUser cmdlet is fixed.

Thanks,
AB#10944

Please push this on top of requirement list, $null should be supported as we have in Set-MSOLUser. The workaround needs extra handling and additional calls.

It would be good if an ETA is shared.

This needs to be updated/fixed such that the "OtherMails" attribute can also be set to null.

This module needs to be at parity with MSOnline before it is retired. Please expedite.

Any updates to this?

Invoke-GraphRequest fails on the latest module version 1.14.0. You can use Invoke-MgGraphRequest instead.

Invoke-MgGraphRequest -Method PATCH -Uri "https://graph.microsoft.com/v1.0/uers/ -Body "{ "mobilePhone": null }"

As multiple customers are facing this issue, please fix this asap.

@rui0122, the workaround works well for me in v1.14.0:

The issue is with the spelling of users in the -Uri.
