Correct. I'll try to dig up some links (there are KBs out there now on this; there were originally none).
What matters is the "critical path" - both for common user operations and background tasks, Outlook in Online Mode+Exchange will keep a "view" of the Inbox,Sent,Calendar and I think one other folder. Exchange can't keep this view for every mailbox always, so some are always being overwritten. When Exchange has to re-generate that view, a large number of total items in it will degrade performance. Factor in an already overtaxed Exchange server, and the problem can have a very real client performance impact. For other folders (including user-created top level folders), the item count matters for views to be created, but they aren't in the "critical list" and won't be created unless needed by a client. Likewise - Outlook Cached Mode will greatly reduce this impact on the server, but things like archive products, VSAPI, delegation of folders are all back to Online mode. --James On 3/25/09, Webster <[email protected]> wrote: >> -----Original Message----- >> From: mqcarp [mailto:[email protected]] >> Subject: Re: Large Mailboxes Performance >> >> For clarification, are you suggesting that the count be under 5,000 >> for inbox and subfolders, or just the inbox?
