Have created a service that sends alerts to users via OCS 2007 R2. One of the testers messages are going straight to history. Her configuration is Windows XP with Outlook 2003 and OCS Communicator 2007 R2 ( in know antiquated ). She said originally she was receiving them and then they stopped. She then found them in history. The only server side change was to Terminate the conversation and the InstantMessageCall and I do believe that happened a few hours before she stopped receiving messages. She says she has made sure that the service user isn't blocked.
Any ideas?
