Every time I compose or reply to an email message, and then attach a file, Outlook crashes. When I click the button to attach a file, the dialog box comes up, and the mouse shows that the computer is thinking. Then, windows says that outlook is not responding and then Windows tells me that Outlook has encountered an error and needs to close. I can send a regular email message without attaching file. And I can do everything except attaching a file. I have restarted my computer and outlook,but it still doesn't work. And I have searched Google, and I do not want to pay $50.00 to call MS. Please help me! Thanks.

I wonder if something is wrong with my system. I now cannot start Microsoft Visual C# 2008 Express edition. I need some help Fast. Thank you.

This may be a long shot, but are you on a network with networked drives? The other day I started getting messages at startup that said something like "Could not complete all network connections". I could access all my files, so I ignored it. Then I noticed that when I would chose Save As from an office program and click on the down arrow to change the location of where the file would save, my system would hang, the program would become non-responsive and I would have to force-quit. I finally decided to address the "network drive" issue and it turned out that a corporate drive that I no longer used (but I was still connecting to) had been taken off line. As soon as I deleted the drive from my network connections folder, all my Save As problems went away. Could it be that you have a network drive that is no longer "valid" and it is crashing Outlook when it tries to open the attachment window and load all of your paths?

No. I do not have any network drives. I have my main HDD which Windows is installed on and a secondary (Slave) HDD which I use to store everything else.

Ok, I found my problem, now I just need to fix it. I read an article online that said that some people have problems with Outlook and malware. I used this MS Office diagnostics program that looked for problems with the Office software. It found one problem, under the "setup" category. So it said it fixed it, and I rebooted the PC. Then, when I go to open Outlook, an error message comes up saying something about Outlook not being able to open because of Malware. So I am scanning the PC now with Grisoft AVG. Will that take care of the Malware?

Have you installed Office 2007 SP1? Life's more painless for the brainless.

AVG did not find anything. I will try "Malware Sweeper". Let me know if you have any suggestions. Thanks
