[cisco-voip] Cisco Unity Unified Messaging with Exchange 2003

[Ed Leatherman]

Rebooting Unity generally works for us. usually our windows networking
folks tell me ahead of time when they are going to reboot exchange
and/or GC server, and I just schedule a unity reboot for a few hours
later (usually ends up being 3AM). One thing to keep in mind if you
have a large number of mailboxes - when you reboot it's going to be
resynching MWI lights, and its a slow process (takes an hour+ for us
with 4000 mailboxes last time I cared to time it). Also, I'm not 100%
sure, but I think while this is going on any state changes for new
messages are going to get queued up behind the resynchs in the
notifier queue.. which would just make it seem worse until it sorts
itself all out.

Are there any SR's for your version of Unity? Might be worth
researching to see if there are any MWI bugs. We seemed to have fewer
MWI problems when we moved to 4.1 from 4.0.x. (we're on 5 now). We
still reboot after any exchange or GC/DC patches though.
