Outlook 2007 Slow To Open Messages With Attachments

I recently had to reload my Vista machine and this weekend I installed SP1 for Office 2007. This week I've noticed that Outlook 2007 was very slow to open messages that had attachments. After much digging on the Internet, I finally saw a comment from someone that mentioned turning off Attachment Preview to speed up Outlook. So, I went to

Tools -> Trust Center -> Attachment Handling

and turned off attachment preview. This solved my problem!

Thank you Lazy Web!

Updated 04/24/2008 2:26PM: WRONG!!! Turns out the problem was Symantec Antivirus. Don't know how to fix it, so for now I've disabled the email scanning. :-( Not happy.

Corporately I am stuck with Symantec at work and can't disable it. However, turning off the preview really helped my problem. Thanks for the tip!!

Open Outlook and go to Tools->Trust Center
Navigate to Add-Ins in the left column
Select COM Add-ins in the Manage drop down and click Go
Uncheck any Norton or Symantec product and Click OK

Here's how I did it for Outlook on an Exchange server. It's similar to the 2nd comment, but different in the last couple of steps:

1) Open Outlook
2) Go to "Tools" in menu bar
3) Click on "Trust Center..."
4) Select "Add-ins" in the left menu
5) At bottom of window for "Manage:", select "Exchange Client Extensions" and click "Go..."
6) Uncheck your antivirus software name (mine was "Symantec AntiVirus 10.1")
7) Click "Ok"

Effects should be immediate!

The tip involving disabling using the add-in manager worked like a charm.

Stupid Symantec.

There are many tools on my computer. Yesterday I had unpleasant difficult problem,which I didn't know how to restore it. But for luck I entered the Internet and observed there an extraordinary software - microsoft exchange moving outlook ost file. I used the utility and it determined my issue for a minute and free of charge as I kept in mind. The software restored my crashed emails completely easy.

Disabling using the Norton add-in worked for me! From 3 mins to open an attachment to 3 seconds.

Note that I had to reboot to get it to pick up the changes. (I think Outlook is caching itself somewhere since it opens instantaneously on my old PC. But it wasn't worth the trouble to figure that out when a reboot worked.)

You made my day. Disabling email scan in Symantec itself didn't change anything. But disabling the exchange add-in did the job. Down from minutes for opening an email with attachment to 1sec. Thanks!

One day if I had chosen wrong resolution I would have lost all my Outlook emails. But could make a right decision. I downloaded one program from one forum and it effortlessly solved out my troubles. Moreover I believe it would be good choice for settling this question - how to fix a .ost file in outlook 2003.

Several days ago my friend dropped in at my flat. He told me about one attractive software, which he perceived at the I-net. I used it and was shocked, reason of the application solved out my old troubles with outlook messages. Probably it would help for solving this issue - pst viewer?.

Disabling attachment preview worked, in my case.
