Wondering how some are dealing with deleted user accounts and their email accounts? I show a ton of warnings in the Application viewer stating event ID 9548. Disabled user /O=domain/ou=site/cn=recipients/cn=username does not have a master account SID. Please use AD MMC to set an active account as this user's master account. We have a policy in place to leave the disabled for 30 days. Is it best to just ignore the errors in the event log or can the accounts themselves also be disabled to prevent the errors from appearing? Looking at the Exchange Tasks on the account it only gives an option to Move or Delete the mailbox. Hopefully this doesn't come across as too dumb of a question for a response. TIA
