Laurie writes: I have a Mac, iPhone and iPad and I use Apple Mail. When my husband sends or forwards an email to me from Outlook using his PC, the attachments arrive as “winmail.dat” and I can’t open them.
Winmail.dat or ATT0001.dat attachments are TNEF encoded files sent by Microsoft Outlook and Exchange. Users with other e-mail clients (like Thunderbird or Lotus Notes) or platforms (like Android, Apple, iPad or iPhone) cannot natively read the winmail.dat files. For more information on TNEF files, see our Winmail.dat files section. Winmail.dat file is a Microsoft proprietary Outlook/Exchange format. The most convenient way to view this file is to use a converter program. There are many available. For instance, this is a free online converter that you may use to open the “winmail.dat” file. Another option is to use the TNEF’s Enough for Mac OS app, which is also.
Every search I have made on this subject says that this is just a problem between Outlook and Mail. Many forums recommend 3rd party software to open the attachments. You have got to be kidding! We shouldn’t have to be bouncing around with multiple programs just to do something as simple as see an attachment.
Is there a setting I am missing? https://boundheavenly768.weebly.com/minimum-requirements-for-mac-os-el-capitan.html.
Hi Laurie! Nope, you’re not missing anything—and yes, there are occassions when Outlook and the Mac’s Mail app don’t play well together.
Specifically, Outlook has its own, unique method for formatting email messages that many other email clients can’t quite decode.
When that happens, the body of the message turns into an attachment named “winmail.dat”—and no, your Mac can’t open it without help from a third-party program. Annoying, but true.
Too many mail messages arriving as “winmail.dat” attachments? Windows users can set Outlook to disable the culprit: “Rich Text” formatting. Exit 0 in dev c++.
Deleted arlo app for android and my downloaded videos disappeared. The good news is that your husband can set Outlook to deactivate its so-called “Rich Text Format” (which lets Outlook users compose messages with fancy fonts and other features) when sending messages to non-Outlookers.
