In the past 4 months or so I notice that whenever I attach something to an outlook email it takes a huge amount of time to attach, like 20 to 30 seconds on average, no matter what size the attachment. This is only for the first attachment however. All subsequent attachments into either the same email or any other new emails in the same Outlook session all attach quite quickly (1 to 3 seconds on average depending on the size). Even if the subsequent attachment attempt is the exact same file as the first attachment it goes quickly. Attaching didn’t use to behave this way.
What I have done
1- So I first started with Outlook since besides the slow attaching, all of Outlook was somewhat sluggish. So I cleaned out my personal folder reducing the size from over 700 Mb down to 400 Mb. That cleared up the Outlook sluggishness right off but it did nothing for the slow attaching.
2- Suspecting a virus I ran a full-system virus scan twice using Trend Micro’s PC-Cillin Internet Security 2007, which is current and up to date. It found a number of spyware infections the first time but no viruses. The second time it found only 1 or 2 spywares and again no viruses.
3- I read through the Outlook forum and found <post:=653,502>post 653,502</post:> which describes a problem quite similar to mine. But none of the responders successfully solved the problem for that poster (rlweiner) and none of the suggested causes apply to me. With my experience of the problem I can actually hear the hard drive churning away for the duration of the long attaching. So for me its more of its very busy doing something that is taking way too long than rlweiner's experience of it hanging.
1. What is causing the extremely slow attaching for the first attachments?
2. Could this be some sort of virus (even though scans detect none) that gets run only on the first attach and does who knows what (maybe copying my contacts for some illicit purpose)?
