Re-enabled user in AD cannot access own mailbox (Access Denied)
Posted on 2005-05-04
Hi Experts, I recently disabled a user in AD (Windows Server 2003) due to security reasons. Next day, I re-enabled this user but when user runs outlook 2002, message shows that access is denied.
Overnight the Information store was stopped for a backup to run and later restarted. Since restart of Info store, server logs Event 9548 which states that the user "does not have a master account SID. Please use Active Directory MMC to set an active account as this user's master account."
I have found an article which explained that I can place a tick in the Mailbox Rights (Associated External Account and Full Mailbox Access) but this has not helped. do I need to restart info store?
I am very confused. Is this a security measure or a bug in Exchange 2003? How do I get this user's access to his own mailbox back? Please help and thanks in anticipation....
