I use public namespace for group mailboxes. Users are able to create subfolders , but its impossible to delete them. thunderbird 2.0.0.21 complains: "Cant' rename mailbox to another storage type", both namespaces (private and public) use same storage type, so I believe that it's a namespace problem.

Yeah, TB tries to delete folders by moving them under Trash.

Is there any way to move folders between namespaces?

Not currently. I've thought about adding support for that, but there are also some potential security issues with shared mailboxes.

Or maybe sieve script or plugin which intercept move command and do the move to some unsibscribible folder in public namespace.

Sure a plugin could do that, but you'd have to write it..

I don't really have any good solutions right now, except to use some other client to delete the mailboxes.
