I've seen lots of threads go by about importing e-mail from one program to another, and my case is seemingly simpler, but I have had no luck so far. I want to import into Entourage the e-mail from a backup of the disk. I know how to import mail into Entourage from other e-mail programs and I know how to import mail into Entourage from an archive created by exporting from Entourage, but I cannot figure out how to import from a backup of the folders under the "/Users/(username)/Documents/Microsoft User Data" folder, under which is where Entourage stores mail. More details: It's not my own system. I am helping a friend who has Entourage 11.21 as part of MS Office. His mailboxes are currently empty because he has reinstalled his whole system (Mac OS and applications) on a new disk. All of his old mail is on another disk created with a disk-to-disk Finder copy, and he wants to import the old mail into Entourage. When I try to import, however, Entourage offers me three choices, none of which seems to work for this case: 1. "Import information from an Entourage archive" 2. "Import information from a program" 3. "Import information from a text file" The first choice looks only for .rge (Entourage archived mail) files and can't be used on the old mail folders directly. The others don't seem to handle Entourage folders either. You can tell because when they put you in a File-Open dialog box (to locate the data to import), there is nowhere you can navigate to under the "Microsoft User Data" backup that is not dimmed. Does Entourage let you do what I'm trying to do? I can think of another method to try: replacing some of the subfolders in the entire Microsoft User Data folder with the same folders from the backup copy, and hoping Entourage is "fooled" into finding the old mail. But first I'd like to know if there's a proper way to do this.
