Why do I receive a file winmail.dat when other MAC devices get a regular attachment?

I'm going crazy over this one. About a month ago, my partner's email attachments began appearing as (unreadable) winmail.dat. I've the issues on this forum, about rich text vs. plain, etc. But I can't understand why on my Mac devices (laptop, ipad, iphone) they come through like this, while on my friend's device, they come through as .doc or pdf or photos.

Do I need to adjust a setting?

I use me.com (icloud). When I forward to gmail, I can download. But I shouldn't have to forward to gmail to get the info.

Any wisdom would be wonderful!

We're both with the same ISP...

I went through all the preference settings in Mail and they're identical.

No, I'll send it from my work email to both her home address and my home address all from one email.

I spent hours trying to fix this problem and the deleting contact and reentering was the fix. Kudos.

Yes!! Deleting the contact info solved this irritating problem for me after weeks of trial and error. Thanks!!

I also suddently started getting this problem in different computers and users.

Deleting the contact information is not a solution in my case.

I believe it might be a bug in Mountain Lion?

So wonderful for a simple (yet elusive) solution to my problem! Now my husband will once again have an updated calendar and not excuse for not knowing what family plans are :-)

This appears to only work if the only thing in the .dat file is a single pdf or jpg.
