Drag and dropping email from outlook desktop to Edge doesn't populate dataTransfer API in certain cases

Ariel Daza 1 Reputation point


I've noticed if an email inside the outlook desktop client meets the following criteria

  • Sender name is single
  • Sender name in single and the subject has a word before ":"

I have Outlook 2019 desktop installed Microsoft Edge(87.0.637.0) and Google Chrome Versión 91.0.4472.114 (Build oficial) (64 bits).

These are my error cases.

Case 1
From = TestName
Subject = RE: test subject
Received = 11:25 PM
Size = 72 KB
Categories =

Case 2
From = TestName
Subject =
Received = 11:24 PM
Size = 72 KB
Categories =

When dragged directly from the client to Browser The dataTransfer API picks it up as "uri-list" instead of a file, see screenshot below

    Hello @Ariel Daza

    we have encountered the same issue with Outlook 2019 and also confirmed it needs these three conditions:

    1. The sender name is a single string without spaces, e.g. "JohnDoe"
    2. The message subject contains a Re: or FW: prefix
    3. The "Show as Conversation" view is not enabled in Outlook

    This can be reproduced with Edge and also Chrome browser.

    We found that enabling the "Show as Conversation" view in Outlook could help as a workaround, as it's changing the subject to the conversation topic which doesn't have Re: or Fw: prefix. Then the drag & drop works. We opened a case with Microsoft to see what they can find.
