Looking to make a rule for external emails to 10 or more users RRS feed

  • Question

  • Hello,

    I am looking to make a rule that states the following:

    Anyone Outside the organization that emails 10 or more users Internally has to be redirected to me for approval.

    I am able to find the Outside the Organization in the create rule guide and have it set to forward to me for approval. My problem is, how can I find the option that states "10 or more users" without being specific on the users.

    Any help? Thanks in advance.

  • You cannot achieve this with transport rules, as there is no condition to detect the number of recipients. You will need to create a custom transport agent.
