Re: copy shared folder to user inbox

Hi Michael,

Thank you for the hints.

I'll be migrating mailboxes to Fastmail Business through their web GUI 
import tool.

It works like a charm when I specify IMAP URL, port (993), username and 
password.

I've managed to move a shared folder (luckily a tiny test one) by:

cyradm
sam testfolder testuser lrswipkxte

Then I logged in as testuser to Thunderbird, subscribed to that folder 
and copied it to inbox.

Despite selecting "copy" (not "move"), the folder was moved on our Cyrus 
IMAP and now only exists in one user's inbox!

Any idea how to copy rather than move?

Is it even possible for Cyrus to make or hold identical copies?

Regards,
Adam
