Hi, have an Exchange 2010 Hybrid setup
I have created distribution list in Exchange console and also distribution group in AD
Synced successfully, tried to send a mail to email@example.com
Get following error
The action 'Set-DistributionGroup', 'RequireSenderAuthenticationEnabled', can't be performed on the object 'firstname.lastname@example.org' because the object is being synchronized from your on-premises organization. This action should be performed on the object in your on-premises organization.
Have unticked Require that all senders are authenticated in Message Delivery Restrictions as sent a test mail and get below error
The group test.test only accepts messages from people in its organization or on its allowed senders list, and your email address isn't on the list.
Any best way to fix it?
