Recipient name is different than domain mailbox name

Question

We have a hybrid azure active directory and one of our users is hidden from the global address book. When I try to un hide it using the Exchange, it says it is managed by the on-premises directory. So, I then go to the user in the active directory on-site and go into his profile, then to attribute editor. The "HiddenFromAddressListEnabled" is set to <not set> for this user.

When I run the powershell command Get-Recipient -ResultSize unlimited -Filter 'HiddenFromAddressListsEnabled -eq $true' the results show the UserMailbox is listed in the results. However, the name is wrong. Instead of the user named "firstname.lastname" it is labeled "firstname.lastname_domain-1".

I believe the username and everything is synced appropriately for most things in azure active directoy including SSO, but the exchange information does not seem to be matching up completely. There seems to be a duplicate onmicrosoft.com name in exchange for this user that has different hide from GAL settings than what is set for the on-site active directory. How do I change this exchange "HiddenFromAddressListsEnabled true firstname.lastname_domain-1" to "HiddenFromAddressListsEnabled false firstname.lastname"?

Answer 1

Please try to update UPN via Powershell:

1. Open PowerShell & connect $msolcred = get-credential connect-msolservice -credential $msolcred

Update the user name:

Set-MsolUserPrincipalName -UserPrincipalName name.surname@Company portal .onmicrosoft.com -NewUserPrincipalName name.surname@Company portal .com

Answer 2

PS C:\Windows\system32> Set-MsolUserPrincipalName -UserPrincipalName first.last_contoso-1@Company portal .onmicrosoft.com -NewUserPrincipalName first.last@Company portal .com
Set-MsolUserPrincipalName : Access Denied. You do not have permissions to call this cmdlet.

I am a global admin, so I know I am supposed to have the appropriate permissions and should not be getting an access denied.
I am not sure where the Get-Recipient command draws the name from, but the UPN seems to be correct for this user, it is a different naming designation that is mismatched. His mail works fine, he can use all the SSO login just fine. The only thing that doesn't seem to connect right is the attributes from the on-site DC to Exchange online. All the "first.last_contoso-1" should just be "first.last"

When I run the command: Get-Recipient -Identity 'first.last_contoso-l' | format-list
the results are below:
Identity : first.last_contoso-l

Sorry, about it being posted a few times. When I opened the window, it was not populating so I added it again. I will try to clean the repeats out.
