Ok so i know a lot of you have probably seen people going on about this problem before and it sucks.

Outlook simply refuses to act as it should on one workstation.

I recently upgraded a workstation to Windows 7, installed Office 2007 on the machine and imported the users .PST. (The PST is around 4GB in size).

I've tried all of the following:

• Archived Emails and created a new profile.
• Disabled all Addons.
• Deleted the PST

I have no idea what to do now. I found that opening outlook in safemode worked fine for a couple hours and then decided to completely slow down again, then if i restart in safemode it speeds up but it's getting irritating and i'd rather just have it working.

There is also a problem when typing in someones username it sometimes takes 2mins to autocomplete? WTF thats just crazy, looking around that could be something to do with the .NK2 file?

Has anyone got any other suggestions because otherwise i'm going to have to give the user a different machine and swap all documents etc over.

Cheers!
