From our smartphones (running Mobile 6.1 and Communicator mobile 2007) we are able to successfully use communicator - however periodically (perhaps every 15 minutes) we get the following error message "An error occurred. Please contact your system administrator with the following error code. (ID: 800ee008a)" - our Communicator Mobile client then goes "offline". We can sign back in fine. Does anyone know why? This happens regularly (perhaps every 15 minutes.)
