Thor, I help support an Exchange 2003 environment where we have about 16 mailbox stores, each about 100GB in size. What specific kind of mailbox store management are you asking about? Archival, backup/restore, policy enforcement? How many mailboxes make up that 90 GB? Are you on SCSI, ATA, SATA, or SAN storage? How big are you looking to grow? Do you have any compliance (FISMA, HIPAA, FDA, SEC) policies you need to follow with regards to retention? The answers to all these questions will drive your Exchange design and really set the pace for "best practices". Cordially yours, Jerry G.

Actually, we have used 3rd party attachment removal software on old emails, assuming that is part of your problem. It works great, maintains email store setup, saves attachment to network drive you specify, and leaves hyperlink in email to attachment. Only cost $30 or so from Sperry Software. -----Original Message----- From: Thor (Hammer of God) [mailto:Thor@xxxxxxxxxxxxxxx] Sent: Monday, March 13, 2006 2:55 PM To: [ISAserver.org Discussion List] Subject: [isalist] OT: Good source for Exchange Mailstore Management http://www.ISAserver.org OT: Anyone out there working with really big Exchange mail-stores and have a good source for related "best practices" regarding mail-store management? Mine is over 90gig, and I'm looking for particular recommendations that you have found valuable rather than the canned "do this, do that, lick this, etc." Thanks. t
