Hi all, I just recently upgraded a number of PCs from OL2003 (connecting to Exchange - not cached mode) to Outlook 2007 w/ Business Contact Manager (oviously cached mode as this is required). The BCM database is on a shared PC using the BCM database tool. I had experimented with one PC taking it off the cached mode and it had made things speedy again, but I can't keep it like that due to the need for BCM. Any clue what is going on here? Is it cached mode or BCM causing the issue? The speed issues range from starting an email reply and having to wait for what you type to catch up, to slow response if you click on another folder in your mailbox. It's just hurting the Outlook 2007 experience because performance is horrible. Please help! Thanks, Mike
