There is nothing wrong with this exchange (other than the fact that  
Exchange doesn't list the INBOX as "subscribed", but we already work

You will need to debug further and find where your sever is having  
issues.  Try looking at javascript log on the browser or setting  
Horde's logging to debug and then looking for errors.
