I found an interesting problem from some of our users. The problem reported was that if they open an msg attachment in Outlook 2003, it opens the first time but if they close the attachment then try to open the attachment again, they get an Operation failed message. I could open any other kind of attachments twice with no problems. I created an Outlook profile for myself on their computers and got the same problem so it's not a profile problem. I noticed that this problem affected many users on a same section. I was finally able to zero in on the only difference that distinguishes the users with this problem from those that don't have the problem. All users with this problem all uses Adobe Acrobat 8.0 Professional. We use Office 2003 with SP2 on Windows XP. I suspect that if we can find the API from Adobe for Outlook we can fix this problem but don't know which one it is or how to proceed. Did anyone seen this before?
