Plugin Set to Use Offline but Entity Offline Settings Not Configured
While attempting to deploy a solution to CRM 2011 I received the following error during the import.
0x80040203 - Supported deployment does not agree with message availability
After reviewing the code for the plugin I realized that it was attempting to register the plugin for both Server and Offline.
The problem there was that the Entity was not set for Offline mode.
One the entity was updated the solution installed correctly.
