Explanation

This Warning event indicates that the specified account is authorized to use the Receive connector to accept inbound messages, but the account is not authorized to use the Exchange Hub Transport server or the Edge Transport server that contains the Receive connector. The specified account requires the MS-Exch-SMTP-Submit permission to submit inbound messages by using a Receive connector.

Receive connectors use permission groups to define the entities that can submit messages to the Receive connector and the permissions that are assigned to those groups. A permission group is a predefined set of permissions that is granted to well-known security principals and assigned to a Receive connector. Security principals include users, computers, and security groups.

For more information, see Managing Connectors.

User Action

To resolve this problem, verify that the account that is specified in the event text has the MS-Exch-SMTP-Submit permission assigned to it on the appropriate Receive connectors on the Hub Transport server or on the Edge Transport server.
