Winmail.dat files

I have been having some problems with receiving emails that have attachments (Word Docs), but I can't open them because they appear as "winmail.dat" and not an actual Word document. Is there a program that would help me to be able to read these?

There's some info on what they are and why you get them given in the following document:

When I send out mail from MS Outlook enterprise account in the office to my Mac at home they are received as "winmail.dat" files. Even if I perform a "save as" to the correct file name the file format is still not recognized. Why is this happening!?

".dat" is a data file. Adobe Reader can't open it.

Klammer - no permission to open winmail.dat files

Up to now I have been able to open Winmail.dat files without a problem. Suddenly I get the response "Not permitted to open the file"; When I check the file in Finder I have the rights to read and wright. Here I am stuck. Would appreciate some advice.

Try enolsoft winmail viewer. It works well for me and supports Mavericks. You can find it from Mac App Store.

Opening Winmail.dat files in Mail on iPad (Ms Windows Word, Excel, Ppt)

I thought I'd share my findings on what to do if your Word, Excel, Powerpoint attachments come into your Mail as winmail.dat files. In my experience I downloaded the following Apps:
Pages
Numbers
DocsToGo
WinMailViewer
Letter Opener
To open the winmail.dat file hold the icon until asked how you want to open the file: WinMailViewer or Letter Opener (assuming you've previously downloaded both Apps).
WinMailViewer is exactly what it says ... a 'viewer' of the file. The file is sent to the relevant App which you subsequently open to see a list of the files.
Letter Opener will bring up the attachment(s) in a separate window and gives you choices on which App you'd like to use to open or view the file with. Depending on what Apps you've previously downloaded:
For Excel it might list: Quick Look, DocsToGo, Csv File Editor, PDFReaderLite
For Word, it might list: Pages, DocsToGo, PDFReaderLite
DocsToGo is an excellent option for working on Word, Excel files (N.B. If you have a big Excel file with 'frozen' window panes, I recommend clicking on the 4th tool (bottom toolbar) UnFreezing the panes while you work or move around the file as I haven't figured how to work with it on!!)
Pages is the best option to use for editing Word files.
Numbers is probably the best option to use for editing Excel files.
Csv File Editor is another Excel editing option.
I hope that helps.

I should further say the files I sent are .xlsx and .docx files. They look fine my end and I send such files all the time without problems.
However, I did try to cheat by going in via the Safari onto my 'live' online email account and the Safari automatically transfers them to winmail.dat files with the same result.
Ahh - have just been on using my PC this time and you are right, it seems that the service provider does the transfer and then when my outlook opens the file (on the PC), it must reconvert to .xlsx etc again.
Very strange.
Ergo, I guess the question should be how I open wimail.dat files ??

HT2614 Is there a way to open winmail.dat files on a mac pc?

aparently winmail.dat files ar created by microsft outlook or simular mail clients on a PC and has somthing to do with rich text document settings. if i start my computer in windows mode i can view the files however if i start in MAC OS and try to open it wont reconise even if using the MAC version of Microsft outlook.

That's a Microsoft extension. For frequent email senders, you can request they stop sending the Microsoft-specific stuff; messages that aren't directly readable by other mail clients. Here's how they can disable this: Email received from a sender using Outlook includes a Winmail.dat attachment (Microsoft KB278061)

Open winmail.dat files?

Anyone know how to open winmail.dat files? I've been getting email attachments which I can't open on my MBP.

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.

How to advoid Pdf attached files turning into winmail.dat file causing incovinience opening them? And why does the phone automatically changes the file???

The first time i opened the mail, the mail loaded the attactment as pdf file and i was able to open it without any problems. But then when i tried to open it again, i watched the phone automatically turned the pdf file into winmail.dat without any of my control. Since then, i werent able to open the file anymore! And this was lucky that i was able to see it as pdf file - all other attachments i have recieved since using my new ip6 all turn into winmail.dat
this is really incovinient and frustrating for work. i cant believe i cannot just open a pdf file as a pdf file on my ip6 in the emails i recieve. I was on ip4 before this and never have anything like this happened.
Solution needed asap please.
Thankyou!

Hi Jnkm,
I'm sorry to hear you are having issues with your new iPhone 6. If you are getting a winmail.dat file instead of a PDF, you may want to see if it may be the issue noted in the following article:

Opening winmail.dat files on iMac

I just purchased a new iMac for home use, but I still use it quite a bit for business purposes. As such, I receive quite a few emails from Outlook users and people on Exchange servers, and consequently much of my email on the new Mac ends up as winmail.dat files or attachments. Incredibly, Apple support says that the asnwer is simply to tell all my emailers to change the way they send their mail! I can't believe that there's not a better answer or fix. Does anyone have a better solution?

Hi,
There is a solution...

.docx attachments showing up as winmail.dat files

My wife and I both have comcast.net emails. When the secretary at our church sent both of us the same email with a .docx attachment, and we open the email on our IMac with Mail, it shows up under my email as a .docx (which I can open and read) but it shows up under my wife's email as a winmail.dat file. Why?

Yes. Our incoming mail servers are the same. When i go into Mail Preferences and look at Accounts, everything iin all three areas (account information, mailbox behaviors and advanced) are all the same except for our individual email addresses and passwords.
I just noticed by going back to some older emails in my wife's account that she has received .docx attachments from other church members (and they open up just fine). This would lead me to believe that it would be some setting on the church secretary's computer. I will forward your above referenced article to our church secretary and have her be sure her settings are set as recommeded.
I am still baffled, however, as to why my Mail account has not had this issue, and my wife's has.

Suddenly, my Word docs are showing up on IPAD email as winmail.dat files

I've been sending myself word docs from Windows Outlook desktop email so I can work on documents on my IPAD while away from home. Worked fine until yesterday, and now my word2003 attached docs on Ipad email are showing up as unopenable winmail.dat files. I've done nothing different, so am not sure what is happening. Other people's emails with Word docx files are opening fine as are pdfs

Sorry, I can't help with why it is happening but there is an app available to read them.

That has no effect on emails that you receive.

TS3276 why is jpeg file lost and replaced with winmail.dat file in mail

I sent a jpeg file to my hotmail account, which is synchronised in my Mac Mail but the file was lost/converted to winmail.dat attachment, which I couldn't import to iPhoto. How do I import a jpeg image, emailed to me from an external source, to iPhoto?

I think you need to configure Outlook in Windows to use HTML messages.
Here is Microsoft's incomprehensible support document on the issue.
Here is one from about.com that makes sense.
