Explanation: Starting with GroupWise 6.5, the POA can be configured to require SSL connections with clients.
Possible Cause: Users of clients earlier than GroupWise 6.5 are trying to log in to the post office.
Action: Have users update their GroupWise client software. See "Updating Users' GroupWise Clients" in "Update" in the GroupWise 6.5 Installation Guide.
Action: Configure the POA so that SSL is enabled rather than required, so that the older GroupWise clients can connect to the post office. See "Enhancing Post Office Security with SSL Connections to the POA" in "Post Office Agent" in the GroupWise 6.5 Administration Guide.
