Message Text

The account '%1' provided valid credentials, but it does not have submit permissions on SMTP Receive connector '%2'; failing authentication.

Explanation

This Warning event indicates that the security principal that is trying to use the specified Receive connector does not have the Ms-Exch-SMTP-Submit permission assigned to it on the Receive connector. Security principals are user accounts, computer accounts, or security groups.

The Ms-Exch-SMTP-Submit permission allows the Receive connector to accept the SMTP MAIL FROM: command from the connecting messaging server.

Receive connectors grant permissions to security principals or to permission groups. Permission group members and their assigned permissions cannot be modified. All permission groups grant the Ms-Exch-SMTP-Submit permission on the Receive connector.

User Action

To resolve this problem, do one of the following:

  • Use the Set-ReceiveConnector cmdlet in the Exchange Management Shell to assign the appropriate permission group to the Receive connector. For more information, see Set-ReceiveConnector.

  • Use the Add-ADPermission cmdlet in the Exchange Management Shell to grant the Ms-Exch-SMTP-Submit permission to an appropriate security principal, and then assign that security principal to the Receive connector. For more information, see Add-ADPermission.
