Getting error that I can't send emails to a group?

The error is "Remote Server returned '550 5.2.0 Resolver.MT.NoModeratorAddresses; No moderator addresses for approval process"

 

It is a group for "All Users". It isn't a distribution group so there is no option for me to take off moderated messaging. Please assist!

    Hi DylanFields - You can run the command below to check if moderation is enabled on that group?

     

    Get-DistributionGroup <Identity> | FL ManagedBy,Moderat*

      Hi Dhurava,

      In my case, the group is sync with AAD from on prem to O365. The group is configured with moderator. However when internal user send email to this group, error message of "Remote Server returned '550 5.2.0 Resolver.MT.NoModeratorAddresses; No moderator addresses for approval process" generated.

      Both moderator are still exist

        Hi faizahkhalid - Could you please confirm the below?

         

        1. Does it fail for both on-premises and cloud users who send emails to this group?

        2. There exists a remote mailbox object for the senders and the moderators on-premises?

         

        Regards

        Dhruva
