Had a contractor leave the company and return. Often this creates issues because we don’t run a ‘dead account cleaner’ often enough.

To get around this, I run the script below to get the ‘new’ Active Directory account synced with the new Active Directory account.

Script:

$user = Get-SPUser -web "http://sharepointed.com" -Identity "Mydomain\TheUser"
Move-SPUser -Identity $user -newalias "Mydomain\TheUser" -IgnoreSID 

Where I went wrong… I remoted’ into one of the servers in the farm using my personal NT login. By doing this, I was receiving the error below. Once I remoted’ into the server using the Admin account, I was able to run the script.

Error:
Move-SPUser : Value cannot be null.
Parameter name: userProfileApplicationProxy
