Isolation Mode in Plugins

Isolation mode in plugins describes the level of security restrictions imposed on the plugin execution pipeline.

Isolation mode is specified on assembly level and not on individual plugin steps.

  • If a plugin is in isolation mode, that means it set to be sandbox or none
  • CRM online plugins can only run with an isolation mode = sandbox
  • A normal plugin is a plugin which has an isolation mode = none
  • A plugin registered in sandbox mode is more secure, but some action are restricted, although a plugin can still access the Dynamics CRM organization service
  • Access to the file system,system event log, certain network protocols,registry, and some functionalities like using database or file directory is prevented in the sandbox.
