Its all about the number of items in the core folders, like Inbox, Sent Items, Calendar, etc, and also restricted views. In Exchange 2003, the recommendation was to keep the number of items in these folders < 5,000. In Exchange 2007, the recommendation is not to exceed 20,000 items (as long as youve designed your infrastructure correctly)

Thanks Shay From: Martin Blackstone [mailto:mblackst...@gmail.com] Sent: Monday, March 23, 2009 8:55 AM To: MS-Exchange Admin Issues Subject: RE: Large Mailboxes Performance I dont think large mailboxes from an Exchange perspective are a performance issue. The issue mainly lies in Outlook performance and if your users can somehow learn to control the items in their folders, the performance will be fine. From: Mayo, Shay [mailto:shay.m...@absg.com] Sent: Monday, March 23, 2009 6:38 AM To: MS-Exchange Admin Issues Subject: Large Mailboxes Performance Hey, Just curious what type of performance people have had with large mailboxes on Exchange 2007. Our company has a strict email retention policy that purges email after 30 days, but we have about 200 people though that have special circumstances where they need to store email long term. We implemented an archiving product from C2C about 1 and ½ years ago which turned out to be a far less than desirable solution for our users. We have fully migrated to Exchange 2007 and are kicking around the idea of not having a 3rd party archiving system and just allowing larger mailboxes (3-10 GB) for these special users. So my question is, what kind of performance have you guys seen with mailboxes this large? Do they benefit from Office 2k7 or have they actually ran fine with Office2k3? Lastly, a lot of these users travel and will be using cached Exchange mode. So I am mainly worried about performance from large OSTs .
