Troubleshooting Outlook Performance Issues

13 03 2010

If you ever deal with complaints about Outlook speed, the first thing you need to do (apart from verifying all the latest patches are applied) is to make sure the user is following best practices when it comes to mailbox size (i.e. less than 2GB) . Of course as soon as you enforce or even suggest this you will receive complaints, once the user is shown the performance difference they may come around. This kb from Microsoft offers some additional suggestions. Hopefully this limitation will be fixed in Outlook 2010.
