Hello Everyone, I'm currently running outlook 2007, with a .PST file of about 560MB, and two other .pst files of about 30MB each. All has been running great until about week ago. Now my "outlook today page" will not display and when changing from folder to folder it takes approx 5seconds, which is a huge delay from instant. Here is what I've tried so far. 1)disabled all ad-ins 2)compacted .pst, even though its small 3)disabled AVG outlook scanner 4)repair install office, restarted I'm upgrading to SP3 and running all windows updates, can anyone think what could be causing this? I see others have had this problem, but not a sigle fix has resolved this yet. Hopefully someone can shed some light on this situation. Thanks!

Do you have the Reading Pane open? Try setting Outlook to start in the Inbox rather than the Outlook Today folder. Have you installed SP1? "So won’t you give this man his wings What a shame To have to beg you to see We’re not all the same What a shame" - Shinedown

Thanks Jennifer, Unfortunately, Turning the reading pane on or off does not increase the speed, still takes approx 5secs when changing folders. I just installed SP3 and about 30 extra updates, but it's still running super slow I also tested my RAM and Hard Drive to make sure their is no performace issues. Any other Ideas???

By SP1 I meant Office 2007 SP1; not XP Service Pack. "So won’t you give this man his wings What a shame To have to beg you to see We’re not all the same What a shame" - Shinedown

Just for giggles, In Outlook go to the help menu and run Office diagnostics (used to be detect & repair) and run it to see if it can find any problems.

Jennifer, SP1 is also installed for OFFICE 2007, still slow. Kurt, Disnostics has come up passed.... Thanks again, any other ideas!

Create a new Mail Delivery file and see if that helps. "So won’t you give this man his wings What a shame To have to beg you to see We’re not all the same What a shame" - Shinedown
