You might like to turn it on.  The action of "delete" is classically
implemented as "mark as deleted" and then purge the marked messages
later in IMAP; a "move" message action was originally implemented as
"copy and delete", and that "delete" action left a "mark as deleted"
message in the original folder. This can all lead to a bit of confusion
if you don't know what's going on.

This was all an IMAP server function, not Evolution.

Recent versions of IMAP servers often now implement a proper "move"
function which Evo will use if it's there; that doesn't leave a deleted
message in the originating folder.

Turning on "Show Deleted Messages" will allow you to see if there are
any un-purged deleted messages still present that may be causing
confusion.

It could be that something has changed on the IMAP server side, not
with Evolution. The way that some of the IMAP operations are
implemented might now result in leaving "deleted" messages lying around
that you can't see. There are also some odd IMAP implementations out
there - the Gmail version is one because they have difficulty mapping
IMAP functions to the philosophy of how Google handles your mail; it
might be that web.de is also a "bit odd".

There may be other ways of doing approximately similar things: what
about "flagging" an email that she wants to archive, then periodically
running a filter that moves all the flagged mail to the archive folder.
