I am having the exact same issue. I have a feeling that OCS 2007 CWA is incompatible with BB. Any thoughts?
GET /cwa/AsyncDataChannel.ashx AckID=0&Ck=&UA=true&Timestamp=1201570399151 8443 - 484 0 0
All requests to CWA from BlackBerry are returned with a 484 error code.
From BlackBerry logs:
:<INFO >:<LAYER = BBIM, DEVICEPIN = XXX, USERID = u3f, SIP URI =
>
:<INFO >:<LAYER = BBIM, DEVICEPIN = XXX, USERID = u3f, Account =
>
:<DEBUG>:<LAYER = SCM, EVENT = Finished JobRunner: IMLoginJobRunner-0, available threads in IMLoginJobPool = 5, time spent = 516ms>
:<DEBUG>:<LAYER = BBIM, DEVICEPIN = XXX, USERID = u3f, OPEN GET response code = 484>
:<WARNG>:<LAYER = BBIM, SERVER ERROR>
and it just ends there...
Nothing in the system event log.
Login requests from the device simply hang.
Running BES 4.1.4 (Exchange) and OCS 2007.
Blackbery knowledgebase doesnt event mention OCS2007.
