Well, I'm getting my first introduction to Exchange servers, and this is the first problem I've encountered.

One of our client's Exchance servers is receiving multiple, repetitive Event Log entries regarding Exchange looking for a user who no longer exists. Further investigation revealed that the user was removed from Active Directory, but evidently Exchange is looking for that user anyway as an "unknown user".

How can one go about cleaning up Exchange so that it no longer looks for users that have been removed from Active Directory?

Here are the Event Log entries:

An error occurred while upgrading the ACL on folder [Public Folders]/eAlumni/Web Clients/I-Q/Linfield College/Contacts located on database "First Storage Group\Public Folder Store (EXCHANGE01)".
The Information Store was unable to convert the security for /O=PCI/OU=PUBCON/CN=RECIPIENTS/CN=BMORIN into a Windows 2000 Security Identifier.
It is possible that this is caused by latency in the Active Directory Service, if so, wait until the user record is replicated to the Active Directory and attempt to access the folder (it will be upgraded in place). If the specified object does NOT get replicated to the Active Directory, use the Microsoft Exchange System Manager or the Exchange Client to update the ACL on the folder manually.
The access rights in the ACE for this DN were 0x7fb.

Disabled user /o=PCI/ou=PUBCON/cn=Recipients/cn=AAli does not have a master account SID. Please use Active Directory MMC to set an active account as this user's master account.

BTW, sorry I haven't been around latley. I just moved to Texas and haven't had much Internet access at all. Just got a new job (on my second day here!), looking to get a new apartment soon, and then I should be back to my usual online escapades.
