Did you receive an email that\u00a0included an attachment with “winmail.dat” in the name. This may happen if the email message was sent to you by someone using a incorrectly configured Microsoft email app like Outlook.<\/p>\n

Incorrectly configured\u00a0Microsofts Outlook e-mail app may send e-mails in the “Transport Neutral Encapsulation Format” (TNEF),\u00a0named “winmail.dat”. This occurred because the sender used the\u00a0Rich Text message format (like bold, italics etc)\u00a0encapsulated in the Transport Neutral Encapsulation Format (TNEF), which your OS X Mail app could not recognize.<\/p>\n

A TNEF-encoded email message will contain a plain text version of the mail you received. Thus you may simply\u00a0ignore<\/strong> this attachment.<\/p>\n

You will see this as:<\/p>\n

Content-Type: application\/ms-tnef;
\nname=”winmail.dat”<\/p><\/blockquote>\n

What if I want to open the Winmail.dat file?<\/h2>\n

Winmail.dat file\u00a0is \u00a0a Microsoft proprietary Outlook\/Exchange format. The most convenient way to view this file is\u00a0to use\u00a0a converter program. There are many available. For instance, this<\/a>\u00a0is a free\u00a0online converter that you may use to open the “winmail.dat” file.<\/p>\n

Another option is to use the\u00a0TNEF’s Enough for Mac OS<\/a> app, which is also available on the Mac Store<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
