Dynamic Distribution Group issue in Hybrid Exchange Setup
We finally able to solve this issue while working with Office 365 Support. It has taken a long time due to ping pong between on premises and Exchange Online teams. Anyway, after digging a while - solution turned out be an attribute issue, which solved our problem.
1. we re-run the Hybrid configuration wizard then following command was run on affected Dynamic Distribution Group.
Set-DynamicDistributionGroup DDG1@abc.com -RequireSenderAuthenticationEnabled $false
Hopefully, it may help someone out there. Thanks.

Hey
So eventuallly you didnt need to add proxy address of @tenant.mail.onmicrosoft.com to the dynamic group?
- Hi shai101,
We added proxy address "email address removed for privacy reasons" then used this command to mark authentication attribute to false.
Set-DynamicDistributionGroup email address removed for privacy reasons -RequireSenderAuthenticationEnabled $false
Hope, this helps.
