Set-MsolUserPrincipalName : Access Denied.

Most of the time, you see the “Access Denied. You do not have permissions to call this cmdlet” error message because of a non-existent UPN name in the “-UserPrincipalName” parameter.

To verify this, you can combine Get-MsolUser and Set-MsolUserPrincipalName cmdlets to include this validation check to get some more meaningful error message.

I suggest you replace “Set-MsolUserPrincipalName -UserPrincipalName $365 -NewUserPrincipalName $email”

with “Get-MsolUser -UserPrincipalName $365 | Set-MsolUserPrincipalName -NewUserPrincipalName $email” and let us know the outcome.

Duplicate Users in Office365

 

Both saying synced with AD however only one account exists

I’ve had to manually delete users from O365 during a DirSync deployment. Use PowerShell on the server running DirSync to run these commands:

Import-Module MSOnline

Connect-MsolService  [Enter your Office 365 admin credentials when prompted]

remove-msoluser –userprincipalname UID@UPN.com

If the account is in Deleted Users in Office 365, append the last command with -RemoveFromRecyclebin
