Every time I open Outlook (2003) I get a box -
Fatal Error
Can not clean temporary directory

I click on OK and from then on, everything works just fine. I just
started getting this. Haven't installed anything new. The only thing
that is different from when I was NOT getting this, is that I was away
for a long weekend so away from my broadband. I was using dialup
instead (connected via dialup and THEN opened Outlook and did
send/receive, so didn't have to change any Outlook settings). When I
got back home, back to broadband, this is when this error started
happening.

So, what temporary directory is Outlook trying to clean? I would think
that if it was the Windows (XP, by the way) temp directory, that the
error would be coming up before even getting to Outlook. But the ONLY
time I'm getting this error is when I open Outlook. For instance, I
left computer on while I was gone for a couple hours today, with
Outlook closed. When I got back and started Outlook, I got the error.
So it's definitely Outlook related.

Any ideas?
