Steps to reproduce:

I have received an email that needs some action by some date.
I convert the email to a Task with a deadline.

Actual results:

I don't have any simple way to get back to the email that the task was created. I'd like to go back to the email to:

• Reply to the email (needed to get the task done)
• Look at the conversation that the email belongs (needed to get additional info about the task).
• See if there are new replies to the email (maybe there are updates to the task!)

Expected results:

The UI of the email should now contain some kind of link to jump to the connected task.

The connected task should contain some kind of link to jump to the email in the email list panel, not only to open the email but to see the thread to which it belongs.

Thank you M Lopez-Ibanez, that sounds like an extremely useful RFE. Implementation may be non-trivial, and we have much more basic stuff that isn't efficient on calendar...

Basically we need bug 264270.
