We run a single Exchange 2003 server. The priv1.edb size is pretty large at 51,076,552 KB (48.71GB). I read an online article that said even though Exchange 2003 SVP2 now can have a database size of 75GB, the default size is still 18GB. Since my database is still running I assume the 18GB default size has been changed at some point in the past, but the article said there should be a DWORD entry in Regedit specifying a new Database Size Limit in GB. I don't have this entry in my registry, so I am wondering how I am still operating on a 48GB database size?
Also, we have a few large mailboxes. One mailbox is over 6GB, and a few others are in the 3GB - 5GB range. Is there a certain point where the mailboxes get so large that it is unhealthy for the server or does mailbox size really make any difference?
I want to separate some mailboxes out into a secondary database on the same server. I have already created a second database, and I will start moving some mailboxes over to it soon, so we don't have all our mailboxes in one huge database. I figure this will help offload the data when I do offline defrags or other maintenance things. Is this a good idea for the most part?
Finally, once I do split out mailboxes into two separate databases, will my public folders be accessible to each database? We rely heavily on public folders and I want to make sure separate databases won't affect the public folder operation.
