Error Event ID: 1022 "The disabled Active Directory user account associated with the mailbox in question might not have the MSExchMasterAccountSID attribute populated. "
This is on a user's mailbox whose AD account I disabled.
I want to keep the mailbox for 1 month and then remove it. How do I rectify this? I know there is 1 SID you can use in exchange for disabled accounts, but i don't remember how to activate it.
