Hi @SI ANTOR If you have changed the password thruogh ADUC and user still using his old password , that's means that his computer is not connected to a domain controller via LAN or VPN when user try to logonand it use the old password in the cache to open a windows session and mailbox. To fix it ask user to connect his PC to network before open windows session. Group policy issue confirm that the computer is enable to contact domain controller to apply GPO , from my point of vue , it should be a network issue. Try to check the health of domain controller by running the following command :
dcdiag
repadmin /showrepl
