I've been running Outlook 2000 on my laptop for over a year. Just recently, either at the point when I invoke it, or when it first starts to download email, it goes walkabout for about 10 minutes. During this time, it's completely locked out and I can hear the disk working overtime. Other applications run very slowly during this time. When it has completed whatever it's doing, it runs fine thereafter. This happens every single day. Does anyone have any thoughts? I've got quite a lot of email on my hard drive, is there a threshold after which Outlook needs to do some index re-org's every time it is invoked?
This is one of those issues that people seem to forget about.
You need to think of you email inbox in the same way as your letter box, an inbox is just the same, you wouldn't leave all your mail in the letter box indefinitely (or behind the front door), it is just not practical because that is not what it was designed for. You must regularly 'archive' any messages that you want to save, that will help speed up the loading of your email program.
I also agree with matt1234, you might also have some sort of virus.
