How do I open winmail.dat files
MacBook Air
I've found this workaround: If you Save the winmail.dat file with .pdf on the end, then you can Open that Saved file with Preview. A bit of a drag having to Save the File but this method is free, it works, and luckily I only have one emailer who uses winmai.dat. If I had heaps using it I would probably buy an App.
This is a common problem.
I have found a converion web-site www.winmaildat.com, where you upload the problem file, and it is automatically 'deciphered', and the contents can be downloaded in their individual files.
Depending on how many emails you get with winmail.dat attachments may I suggest my products:
Letter Opener Pro is integrated right into Mac OS X Mail and Microsoft Outlook 2011 and converts these files seamlessly in the background.
Letter Opener Lite is a standalone App to convert winmail.dat.
Cheers,
Christopher

I use TNEF's Enough but I received a winmail.dat today that it couldn't open, but the site www.winmaildat.com could open it. That makes me suspect that there's been some kind of Microsoft update. I hate running data through a site I don't know anything about, so I hope TNEF's still being maintained.
If WINMAIL.DAT files are showing up from only one or two PC users, ask them to delete you (or your email address) from their CONTACTS folder. This worked for me - I had one person whose emails converted everything to unopenable WINMAIL.DAT files. Tried changing this email settings to Plain Text, but that did nothing.
Once he terminated me from his CONTACTS program, no problema.
Guessing the MS CONTACTS program automatically converts attachments .....
StJohnTiger has the fix.
Anyone who has your contact in MS Outlook associated with other accounts that are Exchange Imap users will cause this issue.
Simply have those people remove your email contact and recreate a new one without any association to Exchange or other email accounts.
Works for me.
I used TNEF's Enough and www.winmaildat.com but the Calendar files didn't open as I expected.
So the easiest way is to forward your email with the winmail.dat to a Gmail account and VOILÀ
I think the answer of Apple ""Send to this recipient in Microsoft rich text format checkbox or preference setting in mail client before they send the message." is a vague answer.
My clients don't care if I can open the files they send me. They are not going to change theirs ways just for me.
So Apple should do the right thing and improve Mail app with these feature.
Sorry this is a Outlook issue we dropped outlook because of this too many customers complaining they could not read our mail 90% non mac users. Our It department would fix it but default settings would get changed back every so often; to much of a pain!
A winmail.dat file is an email attachment archive created by Microsoft Outlook. Usually, they contain a copy of the email message, and may contain file attachments (e.g., PDFs, images, etc).
There are several applications on the Mac App Store that can open winmail.dat files, and allow you to view, copy, and save the contents.
I recommend the one by LawBox: Winmail DAT Viewer.
It's simple and accurate; and LawBox's customer service is legendary – it's worth the purchase price alone.
Winmail.dat files are created by Microsoft Outlook.
I'm surprised that Apple hasn't incorporate winmail.dat support into something like Preview; sure, it's not "their problem", but then again neither is our need to view PDF files, Excel documents, etc.
That said, there are literally dozens of apps available to open winmail.dat files. I'm partial to Winmail DAT Viewer on the Mac, and its companion app on iOS, but, as I said, there are literally dozens of options. Go with the one you trust.
Hi,
My work keeps sending me attachments that only come up as Winmail.dat and I cannot open any of them. While exploring ways to resolve this, I came across your post saying turn them into pdfs and tried to do so, to no avail. How did you do it?
Thank you so much for your help in advance!
Using Gmail in Safari to view, download, and open worked perfectly. I was able to download it as a Word doc as well as saving it as a pdf using the print dialogue box.
Other suggestions in re: changing the file name by appending .pdf did not work. Preview was unable to read the document.
Letter Opener Pro does a good job, but $15 update fees and your disabling of the older version whenever new versions of Mac OSX come out get pretty tedious, and expensive, on top of the original purchase price. I think you need to consider a new approach to long term users if you want to keep their business. Winmail files aren't as common as they were , and there ARE other, cheaper ways of dealing with them.
I've had a strange one today.
The meeting notice arrived as a windmill.dat. What makes it even more strange is that the other person who received the notice could see the meeting notice, the other person received a windmill.dat.
Both in the same office, running a Apple Mail server and both with the same version of mail. Bizarre for that one. I got them to download Klammer. TNEF didn't work with the meeting notice.
