Restrict message recipient to/cc/bcc till 20 only if mail is send from outside of organization


  • Hi Arif,


    After lots of research, I think that we are unable to achieve this requirement on Exchange. I checked the mail flow rule, it didn't provide us a condition to configure the maximum recipients limit. In the mailbox features, we can find the Recipient limit configuration in the Delivery Options, but this feature can only help restrict the outbound emails. Your understanding is much appreciated.
