How to Fix Mobile phone = System.Collections.Hashtable issue

AJAY PRAJAPATI 10 Reputation points

Hello All,

I have used the below command to remove the user phone number from Azure AD, using PowerShell,

set-MSOLUser -UserPrincipalName xxxxxxxx -MobilePhone @{ REMOVE = "xxxxxxxxxx" }

as the mobile number was still visible on Azure AD even after removing it at the AD level.

However, after this command now under the Mobile attribute I can see System.Collections.Hashtable instead of the Phone number and Null.

Can someone guide/assist in getting rid of this? Just want to set the mobile attribute to null.

Thank you

    you can modify your command like the following

    Set-MsolUser -UserPrincipalName xxxxxxxx -MobilePhone $null

    The command you used tried to set the MobilePhone attribute to a hashtable instead of null or an empty string which is causing the issue
