I've been under the impression that Ken's mailboxes were version 10,
which seems like they *should* have guids in them. If this is the
case, then it's interesting that the replica is coming up with zeroed
ones.
If his mailboxes are older than version 10, then it all makes sense,
nothing to see here... though it would be good if the sync code detected
mailboxes being too old to replicate and reported that, instead of
naively trying to sync them and crashing out on the guid check.
I guess it's plausible that version 10 mailboxes had a field in the
index for the guid, but that it wasn't necessarily populated? That
might complicate things? I don't know the history here.
