OS: Windows XP
I attempted to backup my Outlook Express 6 message folders and somehow lost several month's worth of e-mail. First I went to Tools>Options>Maintenance>Store Folder and changed it to an OE backup folder that already existed on my desktop. (OK, that may have been my mistake.) My plan was to backup and copy that folder to a Zip disk for backup.
Anyway, when I re-opened OE all my e-mail was from that folder and several months old. Apparently I had previously backed up to that folder.
After consulting the Microsoft Web page dealing with OE, I attempted to restore the old folders by clicking on File>Import>Messages>OE6>Import from an OE6 store directory>browse. I browsed to the former location of store files and get:
"The specified message store could not be opened. It may be in use by OE."
Any suggestions?
