Migrating Email From Outlook (Windows) to Entourage (Mac OS X)
*UPDATE – February 24, 2007* – This post was written almost five years ago; some of the applications described here are no longer available. I also believe there are now better ways of achieving this migration, but I wouldn’t know since I haven’t had to do this again since. If you know of another way of migrating your Outlook mail to OSX, please feel free to post it the comments below.
A couple of days ago I managed to finish migrating my email archives from Outlook on Windows to Entourage on Mac OS X. For those of you facing a similar challenge, here is the play-by-play:
- Import your Outlook mailboxes into Outlook Express.
- Download oe2mbx.exe. This is an open source command line application that converts OE’s proprietary mail format into the UNIX standard MBOX format. (This application had been offline for a while; thanks to Sasha Svitlica for the updated link.)
- Using the Windows command line, visit the directory where your Outlook Express mailboxes reside. (You can find them by searching for files with the *.dbx extension.)
- Run oe2mbx.exe on the .dbx files.
- Change the resulting files’ extension to .mbox
- Copy the .mbox files to your Mac.
- Drag the .mbox files into Entourage’s mail folders pane.
That’s it. Please drop me a line if you have any problems with this procedure or any suggestions to improve it.
Note: this technique should also work with Apple’s Mail.app and other mail programs that can read mbox files.
Another approach
A lot of folks have written to say that they’ve had issues with the approach presented above. It seems the oe2mbx.exe application is not well documented.
Although I haven’t used it, Emailchemy is an application that promises to convert mail to and from a variety of formats. Outlook doesn’t seem to be supported, but Outlook Express is, so you could follow the above approach from step 1, replacing Emailchemy for oe2mbx in step 2.
