Ok, so Outlook 2007 is running like a dog. It’s slow and cumbersome to use. Microsoft has admitted it and pointed a finger at overlarge .PST files. One wonders why Microsoft persists in forcing hapless users to jam all their emails (plus attachments) and RSS feeds into one .PST file anyway. Heaven help the new user who plain doesn’t understand what a .PST file is anyway, much less why it affects their system performance.
Until the folks at Redmond come to their collective senses and offer us an alternative solution, your options are to work around it. Split your emails into multiple .PST files by archiving them and keep your main .PST file at a small size.
Here are Microsoft’s current series of recommendations for speeding up Outlook 2007, it’s a KnowledgeBase article, and here’s a link to an update for Outlook that promises to fix some of the speed issues: Microsoft Outlook 2007 update download site.
I just have to have the final word here… why, in 2007, should are we still bothered by this stuff?
