Finally a real tip to speed up Outlook 2007!
Following these steps:
1. Open Outlook as an Administrator by going to C:Programs/Microsoft Office/Office12 and right clicking on the Outlook exe program. Choose “Run as Administrator”.
2. Then once Outlook opens, go to Tools, then Trust Center, then Addins.
3. Click “Go…” at the bottom and uncheck Outlookaddins.
4. To maximize speed, they recommended to uncheck everything EXCEPT Windows Indexing, which, according to them, is the only useful addin anyway.
When I did this, the speed of my Outlook 2007 improved significantly; although, we will all have to wait for Microsoft to release the update that fixes this issue completely. I hope this helped you.
We have done this and it realy works. ( we also got rid of the Windows Indexing ) Heck of a lot quicker.
