Incompatible File Formats When Emailed

[Vanessa C.]

I have just switched from PC to Mac. When I email Word documents
created in Word X as an attachment, the PC-using recipient gets a file
with the extension .mme. This file won't open in Word for Windows.
When they send the file back to me, I get a .doc file which I can open
in Word X. I'm also sometimes getting emailed attachments that are
titled winmail.dat. One file started out as a .jpg and another as a
..doc.

I'm saving all my files with .doc, .xls, etc.

What is the problem here?

I don't know why that would be happening. What program are you using for
e-mail? If you're using Entourage X, go to Entourage -> Mail and News
Preferences, click the "Compose" box, and, under "Attachments", select to
"Encode for Windows (MIME/Base64)". Make sure "Compression" is set to
"None".

I'm also sometimes getting emailed attachments that are
titled winmail.dat. One file started out as a .jpg and another as a
.doc.

Those files are created by Microsoft Outlook. See FAQ #217 on The Entourage
Help Page for a conversion utility:
