Hi @j prasad ,
It sounds like there could still be an attribute mismatch causing Azure AD Connect to not reflect the changes. Have you made sure to update the Alias attribute as well using Set-Mailbox
or Set-RemoteMailbox
using the steps described here?
-
Set-RemoteMailbox
PowerShellAI ConvertCopy
$alias=Get-remotemailbox <user@domain.com>
Set-RemoteMailbox <user@domain.com> -alias "$($alias.alias)1"
-
Set-Mailbox
PowerShellAI ConvertCopy
$alias=Get-mailbox <user@domain.com>
Set-Mailbox <user@domain.com> -alias "$($alias.alias)1"**
Also, confirm that the attribute is updated in your Domain Controller under Active Directory Users and Computers > find the user that owns the mailbox > right click on them > select Properties > select the Attribute Editor Tab > find the mailNickname attribute.

If this does not work, please share a screenshot of the error you are receiving and confirm what your setup entails.
