The former is available in the sync log, as part of the data that is  
printed when saving the mailbox state. The latter is probably  
available via the IMAP debug log (or performing Horde::debug()  
statements in the relevant places in the code in  
Horde_ActiveSync_Imap_Adapter::.

No idea. Does it go away if you implement the workaround mentioned in  
the bug report (or upgrade your IMAP server)?
