How can I delete duplicate emails in Evolution?

How can I delete duplicate emails from Evolution 2.32.2?

Solution 1:

In 3.2.2, Ctrl-A (select all messages), Message -> Remove Duplicate Messages works for a folder.

Solution 2:

That's indeed a very common and annoying problem, especially if you're using POP email.

There used to be a plugin to remove duplicates, however, it stopped working with some version.

Evolution 3.1, which ships with Ubuntu 11.10, now has that functionality integrated (Message ▸ Remove Duplicate Messages). With 2.32 you are forced to upgrade. In addition, the function in 3.1 seems to be neither efficient nor configurable so you might still end up with lots of duplicates that give you something to do on a boring weekend.
