Hello,

I generate an eml file but the header X-Unsent doesn't work anymore on the new outlook version (windows 11).

How can I specify the mail is a draft ?

    Unfortunately, including the X-Unsent header in .eml files isn't a reliable way to mark emails as drafts in newer versions of Outlook, including those on Windows 11.

    You may try:

    Compose your email in Outlook.

    Go to "File" and select "Save As."

    Choose the file format "Outlook Message Format (*.eml)" from the "Save as type" dropdown.

    Select a location to save the .eml file.
