Hello Robert,

thank you for your fast response.

I wanted to use the Thunderbird archive feature to allow users to move
old mails, they want to keep, to a storage located on another server.
But it would be perfectly OK to just have another folder where they can
drop their old stuff.
Every user should have a quota of 5G in that folder, which is different
from the default INBOX quota.

best regards

Andreas
