The "Winmail.dat" file is a proprietary file format used by Microsoft Outlook to store email attachments. It's a binary file that contains the attachment data, but it's not a standard file format that most email clients can open.

If you've received a "Winmail.dat" file as an email attachment, you may be wondering how to open it. Here are a few options:

  1. Microsoft Outlook: If you have Microsoft Outlook installed on your computer, you can open the "Winmail.dat" file by attaching it to a new email message and sending it to yourself. When you receive the email, you can open the attachment in Outlook.
  2. Winmail.dat Viewer: There are several third-party tools available that can help you view the contents of a "Winmail.dat" file. One popular option is Winmail.dat Viewer, which is a free tool that allows you to extract the attachment data from the file.
  3. 7-Zip: You can also use a file archiver like 7-Zip to extract the contents of the "Winmail.dat" file. Simply right-click on the file, select "7-Zip" > "Extract Here", and then extract the contents to a new folder.
  4. Online Converters: There are also several online converters available that can help you convert the "Winmail.dat" file to a more standard format, such as PDF or JPEG. One popular option is Online-Convert.com, which offers a range of file conversion tools.
