I'm getting strange errors and i think they're all related to the same issue. I'll post one of them here, and hopefully it will point to a global problem.
I've deleted users from AD, and their mailboxes have been purged from Exchange. But I"m getting an event log error:
Failed to create the mailbox of /Odomain=/OUdomain=/cn=Recipients/cn=username with error 0x50c
Additionally, though this user is no longer a member of any distribution lists now that i've removed the user account, people are getting undeliverable errors for this address. Do I have a lingering object somewhere? If so, how can I clean it up? Also, distribution lists aren't showing up in GAL in a timely manner. Lastly, I've organized AD so that I have users separated into their own OU's for simplicity. Now, when some users send to an all employees distribution list which had been set up prior to the ou creation, random people are getting undeliverables to some of the names on the all employees list. Is this common? Do I have to remove and re-add those people to the distr lists?
I tried looking through adsiedit for the object in case it was hanging out there but was unable to find it.
