Due to a corrupt Active Directory (AD) and a single-label domain name, I had to perform a domain migration and rename the domain. I then reconnected the Exchange Server information store to the new domain. However, there still some unresolved issues: ● Under offline address books (OABs), there is a reference to an address book on the old domain that cannot be deleted. The error message states, “Requested operation is forbidden ID no: c1030af1.” When users select ‘Send and Receive', they get the error message: “Microsoft Exchange Server reported error 0x80004005.” ● There are three OAB files in the current directory that keep recurring, even though they are reporting 0 KB. Under Exchange public folders, there is also a folder that can be renamed, but I can't delete it. I receive the authentication request three times followed by “Access denied facility win32 id no 80070005.” ● Despite using Mailbox Recovery, there's still one mailbox that refers to the old domain. I suspect that I need to remove the references and security relating to the old domain from the Exchange database, but I have not been successful in anything I’ve attempted. Do you have any suggestions that will help fix these issues?
