In a recent article, I spoke of Outlook 2007 issues for email marketers (limitations), and as a part of that process, I upgraded to that version on my own desktop. There are a couple improvements I liked, but quickly became so irate when using it that I came within a few minutes of uninstalling it.

At issue is performance. It's awful. Every time your email "checks" for new mail, it locks up for a few seconds. Since I set mine to check every minute, you can imagine my frustration. At issue is supposedly a memory problem....and, fortunately, there are fixes for this. There's a new Office Service Pack 1 (update) that you will want to download. Simply go to the Help menu in Outlook, and select "Check for Updates". This is a smart thing to do on a monthly basis anyways, as the Outlook junk-mail-filter is one of the better in the industry, if you ask me...and you often have to go "ask" for this update using the above method, otherwise it can take several more weeks before it automatically gets sent to you via the Windows Update service.

I also found this post on the web which provided some simple tips for improving the speed of your Outlook with or without the new Service Pack.
