How do I re-associate a user with their mailbox?
Posted on 2010-09-09
Someone kindly decided to do some spring cleaning and disabled a few active directory user accounts for people who have left our company over the years. Unfortunately they also disabled an account which is still in use and has an Exchange mailbox associated with it.
I've re-enabled the AD user account but at the moment the user can't send or receive email so I guess something is broken big time. On our mail server there are several event log messages stating Event ID 9548 and
Disabled user /o=companyname/ou=domainname/cn=Recipients/cn=Fred does not have a master account SID. Please use Active Directory MMC to set an active account as this user's master account.
I've Googled that and this took me to a couple of MS articles, one of which told me to assign the SELF user to that user's access list and grant it various rights. I don't know if that's correct or if something else needs to happen but that was some time ago and nothing has improved.
Can anyone advise on what I need to do - it's pretty urgent!
