[cisco-voip] Unity Connection - Mailbox Stores

[Erick B.]

I am having DRS fail at 1 gig, with mailstores over 1 gig in size.
I've recently split a client into 5 mailstores now to get past the drs
issue.


this is with unity connection 8.02

so drs should be able to do larger then 1 gig? on the ones it fails on
the drs backup process sits at 40% for awhile then fails....

Does anyone know if there is a limit to # of mailstores you can have?
