Outlook 2007 Running Slow

Outlook 2007 is the latest version of popular e-mail client application. The 2007 version is available both as a separate application as well as a part of the Microsoft Office suite. This email client is versatile, powerful and is omni-present on 80 per cent of the desktops running Windows platform.

When using Microsoft Outlook 2007 you will possibly have come across the problem of the program freezing when you are composing an email. This is often frustrating as it could be frozen for several seconds every 30 seconds.

If your Outlook 2007 is running slow and you feel you have enough RAM and processing power to run it (which if your computer is even 3 or 4 years old it shouldn’t be a problem) then the problem more then likely to do with a few simple settings which I will cover here…

Solution 1: Create a new PST. Although the Outlook 2007 PST is essentially identical to the PST format new to Outlook 2003,Outlook 2007 writes additional data to the PST.

If this fixes the problem, import or move your items from your old PST to the new one.

Solution 2: Create a new profile. No need to delete the old profile just yet, just make a new one to see if the problem is fixed.

If this fixes the problem, you can delete the old profile.

Solution 3: Disable Outlook Setup Add-in (Instant Office add-in by Cyberlink). This add-in is responsible for converting meeting requests to recurring meetings and creating calendar and contact folders when saving attachments. It also slows Outlook down.

Go to Tools, Trust Center, Addins and locate the add-in. At the bottom of the screen, select Manage: COM add-ins and click Go. Remove the checkmark from the Cyberlink add-in and close the dialog.


After going through these simple steps you should find that Outlook is far more responsive then prior to the changes. If you find something is not working then repeat the steps above but test each of the boxes 1 at a time to find the one you need and leave all those you do not need, unchecked.
