You are welcome, this is the least I can do.

Well, if the exchange IMAP server does not list the folders, there is
indeed very little we can do about it.

Having looked a bit more in the spec, it seems that forward slashes are
indeed allowed as part of mailbox names, brrr.

Perhaps we should collect that tidbit in some type of FAQ to prevent
future users from becoming confused by this behavior. Amul, may I ask
which exchange server version this is?
