IMAP + Public Folders

Hi,

I have a customer using Exchange 2013 and Outlook 2013. SSl Cert installed mail. and autodiscover. + DNS Setup correctly

All works wonderfully. The Linux users are using Thunderbird, with Exquilla and can also connect to the Exchange 2013 without any Problems what-so-ever.

The Problem arises with public Folders that are sitting in a Mailbox. How can I make them availiable for the Linux users?

Thanks in advance.
