I have been stupid! I was moving my outlook 2000 file to a convenient place to do a back up when I wanted to check I had the correct file. I clicked on it and opene with outlook. My 3.7M of data disapeared and becam 24k. Can anyone help me to find it and get it back. Also my outlook isn't working but the other 3 users on the machine are unaffeted. Thx in anticipation.

You need to change the location of the data file that Outlook opens. One way to fix this is just go to the default Outlook file under Documents and Settings\User\Local Settings\Application Data\Microsoft\Outlook and delete the smaller, unused file. When you next open Outlook, you'll get an error saying that it can't find your default folders and will allow you to browse to fine the correct folder. At that point, browse to the new location of the pst file, and then close and restart Outlook.

Ok. As far as I understand, I'll try to help you to solve your problem. 1.First of all search *.pst file on that computer. Find your original pst file. 2.Open outlook(create new mail account, personal folder, etc.) 3.Right click and select properties on personal folder that you newly created. Find out where it has been created and what is the name of that .pst file. Exit outlook. 4.Rename your original file with the same name of new .pst file. 4.Copy original .pst file over newly created .pst file. That should be it, when you open outlook, you should retrieve back all your emails.
