It's my first Exchange setup as part of migration from 2000 to SBS 2003 R2. Once I started importing user profiles, I got message that I've riched max mailbox size. I went to the server (Exchange - First Storage Group - Mailboxes and tried to raise default values to get at least 10GB limit per mailbox (I have only about 10 users). Unfortunately, Windows doesn't allow me to set values over 2097151 kB for warning messages. Does that means that I cannot use mailbox over 2GB? Is there any other place where I must set "real" default mailbox storage limit for all users? How I can later limit the storage for particular users to, say, limit it to 1GB just for somebody?
