Review: OK, but unlike MAILBOXID and EMAILID, it doesn't say if THREADIDs can change. I suppose it should be the same that in disaster recovery those might have to be rebuilt. But would that require having a new MAILBOXID or UIDVALIDITY to the mailbox? Actually, the question applies to EMAILIDs also. If clients see the same MAILBOXID and UIDVALIDITY, they might become confused if EMAILIDs or THREADIDs change under them.
