Email where did it go!

[PineAppleExpress]

Ok I have my Email set up so it polls my 3 accounts. No problem. I encounter a problem is my folders. I transfer my Emails to certain folders to save them for future reference. When I get a Email I cloe it out and then go to "Tools" / "Move" and select the folder to where I would like to save them. I went back several days later and I do not find any of my Emails in any of the folders. I think I have found all of my Emails. If I use "file explorer" go to "windows" then into "Messaging" The file names are xxxxx.mpb. I also found what appears to be my attachments folder with files in the folder. If I try and open the file it gives me a errpr There is no application associated with... run the application first etc. I would like to ransfer the files to the correct folders. But I also tried to do this after sync and I could not find the Email folders that I set up to hold the Emails. Does anyone have this problem and how can I resolve this.

Thanks
