Yes it does feel like a bug, Date does not suffer from this bug though.
One annoying "feature" using "Copy Folder To" is that I can mark my toplevel
Folders dir. but I cannot select "On This Computer" to store it on the same
level.

I would be happy to test a patch fixing the Received bug as we soon will
have limited storage in Exchange and I want to store a local copy before that happens.
