About this conversion
winmail.dat is what arrives when Outlook sends a message in its own format to a program that does not understand it: the attachments are inside the container, invisible. Here it is opened and the files come out as they were.
Just want to look inside it?
The same tool without converting anything: open a winmail.dat archive and read it.
You are not locked into ZIP
The file is parsed once and stays open, so the format is picked at the end rather than the beginning: the same winmail.dat can leave here as CSV, XLSX, EML, MBOX, PDF, HTML, TXT or JSON. Before that you can search it by subject or address, filter by year, sender and attachment type, mark the duplicates and look through the archive overview.
Questions
- Why did I get this file at all?
- The sender's Outlook packed the message and its attachments into its own format, and your mail program passed the container through unopened.
- What comes out?
- Every file that was inside, with its real name, in a single zip.
- Does it work inside an archive too?
- Yes — when you open an mbox, pst or eml file here, any winmail.dat inside is unpacked automatically.
