I have a question about the following scenario: I have two Outlook on the Web sessions open in two separate Microsoft Edge windows (Window A and Window B).

Is it possible to drag and drop an email from Outlook in Window A directly into the compose box of Outlook in Window B?

I am asking because a user believes they were able to do this previously, but it is no longer working for them now.

Thank you!

Hi Hiền Nhân,

Please notify me if I have misunderstood anything about your question.

The answer is yes, it's possible in Outlook on the web: the email must be dragged from the message list into a compose/draft window. The expected behavior is:

  • Open Outlook in Window A and compose a new email in a different Window B
  • In Window A, select the email from the message list
  • Drag it into the compose body in Window B.
  • When dropped, the email will attach as an email item, typically as an .eml attachment in Outlook on the web.

    Outlook on the web supports drag and drop for moving items to folders, and Outlook add-ins can support drag and drop into an add-in task pane. The provided documentation does not state that an email can be dragged directly from one Outlook on the web window into the compose box of another Outlook on the web window.

    For Outlook on the web, the documented drag-and-drop behaviors in the provided material are:

    1. Move an item to a folder by dragging it to the destination folder.
    2. In Outlook add-ins, drag messages or attachments into the add-in task pane.

    Cross-window drag and drop from one Outlook on the web session into another window’s compose box is not documented in the provided material.
