No, as any web application, Horde is not using disconnected IMAP mode, but:

A lot of effort has been put into our IMAP libraries recently to  
enable and further improve mailbox caching. This was mainly required  
for DIMP and IMP, but I guess that the Kolab drivers could utilize  
these features too.

There are two kind of caches in Horde, session cache which stores the  
cached objects in the user's PHP session, and persistant cache which  
currently has drivers for storing the cache in the filesystem, in a  
memcache server, or in the Zend Performance Suite. Both are used for  
different purposes.
