Outlook Duplicate Emails Advanced Help Needed

Ok, I know why I am having a problem, but I don't know how to prevent it. I have a dual boot system with Vista32 and Vista 64. Both OS are on seperate partitions. I run Outlook 2007 on both OS installs and I only use pop3 mail. I have both installs of Outlook pointed to the same .pst file on a completely seperate drive. Everything works fine except I am getting duplicate emails because one Outlook doesn't know that the email has already been downloaded.

So, I am sharing the pst file, and I'd also like to share whatever file it is that tells Outlook which emails were already downloaded. Does this make sense? I am confusing myself just typing it.

I though about having Outlook remove the files from the pop server once downloaded, but I need them to be there for remote purposes.

Any thoughts? Hopefully somebody can relate.

I am having the exact same problem, and your post is the only thing I have found through seaching. Did you ever find a solution to this problem?

I never found a solution, and soon after stopped using x64. I settled into x86 nicely and didn't see much reason to go 64 bit...for me anyway.

If you find a solution though, please post it so I can learn from it. I am assuming that there is a file somewhere that holds this information, but obviously, I don't know where to look, or if there would even be a way for the two outlooks to share it. Good luck.

Thanks for replying. Perhaps some day I'll find the answer. As it stands now, I will probably settle back into x86 until more 64 bit software is available.
