Anybody happen to know the file extension(s) for the Address Books in Windows Mail, or even better, where they may be located?

  • Thanks, and yes it was for backup purposes. Unfortunately the user does wants to stick with Windows Mail. What can you do? – HMFIC75 Aug 18 '09 at 14:53

The Mail Is located under:

C:\Users[USERNAME]\AppData\Local\Microsoft\Windows Mail\Local Folders

and uses the extension .eml

contacts are saved under


and are saved as a .contact file

  • exactly. but don't use windows mail. many viruses are created specifically for it – The Green Frog Aug 18 '09 at 14:37
  • I believe his intent was to back up windows mail, probably to prepare for a move to a better client? – user6022 Aug 18 '09 at 14:39
  • you can't do much to turn them, try to find out what they don't like about windows mail that another client does well. A good example is contact searching is broken in windows mail, but is pretty amazing in thunderbird. that's how I won a customer over. – user6022 Aug 18 '09 at 15:31

Windows Mail stores contacts as .contact files in C:\Users\username\Contacts


If you're running Windows Vista, try looking at these locations:

C:\Users\username\AppData\Local\Microsoft\Windows Mail\Local Folders


C:\Users\username\AppData\Local\Microsoft\Windows Mail
