The folders - VContacts, VLeads, VAccounts, VEvents, and VTask, are responsible for the synchronization process. If any of these folders stop responding, that means the Exchange Server has lost track. You must subscribe to the folders again to start tracking changes. To achieve this, you must enable the
Monitor Folders checkbox. You will find this option after running the
Monitor.exe file.
