Actually I just ran into this exact problem and per microsoft it is not
designed to handle large individual mailboxes. The actual problem is the
database store being a btree database. You can have problems with
enumeration of the mailbox items. They actually stated that the number of
items is of more of a concern then the size. I have many users on 2 Gigs
each. The often recieve the waiting to retrieve data from "server" pop up.
If you are using outlook 2003 then this will not be as bad and will not
lock up the UI. By splitting the stores we have lessend the problems we now
have 4 stores for 150 users total almost 100 GB.
