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!

Hi ,


The person that is sending you emails, has chosen in Outlook, to use the RTF format, for emailing and or specifically for emailing you. Perhaps this is default Outlook behavior at times.


This results in the winmail.dat file, which is the RTF format, of the attachments that were intended for you.


If the user would configure Outlook, to use the HTML (web) format, for emails, then you would receive the attachments as intended. As well as anybody else.


Apple mail and other mail systems, do not understand the RTF (rich text) format, and probably have to pay Microsoft licensing fees, to be able to use this format.


The options, for setting this in Outlook, differ for different versions of Outlook, but are found generally under

Tools > Address book, for setting a specific person to , use HTML format, and not RTF format, that persons email.

Also, under "Tools" > "Options", > "Mail format", for setting that all emails, will use the HTML format, instead of the RTF format.

since that did not help me I wonder if it has been working for you.

My wife has MacBook Air, 2012. El Capitan. Reads Windows mail with PDF attachment perfectly. I had a MaxBook Pro ('09) and worked fine. I just bought the MBP "13 with Retina and cannot read my emails sent to me from the same office machine. Comes as winmail.dat.

Both machines are on same level. The only thing I can imagine that there was something on the upgraded machines that is now not on my original El Capitan (this was never upgraded, came with EC).


Now, I also want to note that I need somebody less intelligent than the level 10 arrogance, but somebody who is more constructive.

I know this question was posted a long time ago, but I had the same problem and found this forum when looking for a solution. I get emails from one particular company whose attachments always come through as winmail.dat files. Whilst I have not worked out how to stop them arriving like this (which is what I was looking for when I found this forum), I have found a work-around to view them. I simply save the attachment (on the Desktop or wherever is convenient) and then click on the icon so that I can change the file name and then change from winmail.dat to winmail.pdf. I can then open it with Preview. Hope that helps some people because I know it was driving me mad!
