|An internal email distribution group set with an external email address is not able to receive emails from external users. You do not receive Non-Delivery Reports (NDR) as well. This issue is seen on both Microsoft® Exchange Server® 2007 and 2010 versions. |
|The email distribution groups are configured to require sender authentication by default. When it comes to messages from external sources, it is not possible to authenticate the sender. To successfully send messages externally, you need to disable the mandatory authentication of senders. |
To enable the email distribution group to receive emails from external sources, follow the procedure below:
- Log on to the Exchange Server as an administrator user.
- Click Start, All Programs, Microsoft Exchange Server 2007, Exchange Management Console.
- In the Exchange Management Console window, on the left-hand pane, browse to Recipient Configuration, Distribution Group.
- Select the email distribution group from the middle pane and click Properties in the right-hand pane.
- In the email distribution group Properties window, select the Mail Flow Settings tab. For example, the image below shows the Properties window of the email distribution group 'AA Sales'.
- Select Message Delivery Restrictions and click the Properties... button on the top.
- In the Message Delivery Restrictions window, uncheck the 'Require that all senders are authenticated' check box.
- Click OK, Apply and OK again. The email distribution group will now be able to receive emails from the external sources.
- By default, all email distribution groups are set to authenticate the senders, so the procedure above needs to be applied to all email distribution groups that need to receive externally sent emails.
Note: The procedure above is also applicable for Exchange Server 2010.
