Usually this is an indication that BES does not receive notifications from zimbra server about changes. Please try the following in order to resolve this problem:
- restart BB controller or
- check connection with zimbra server on port 7071 by executing "telnet 'zimbra server ip' 7071". Port 7071 has to be open.
- enable zcb logging and post the snippet of the log with 'BlackBerryAgent' component in the name containing 'WaitSetRequest' and 'WaitSetResponse' keywords.
- if simple steps above do not help, then we may ask to open up support case and supply more logging info |
