Answer 1

Did you assign a matching admin role to the service principal corresponding to your app? The "Exchange Recipient Management" role or equivalent role/role group in Exchange Online is required.

Answer 2

Hi，@Mariyada, Ajaynath Reddy

Thanks for posting your question in the Microsoft Q&A forum.

When you run New-DistributionGroup, a message appears that the command is not recognized.

If only administrator role are not enough, a query reveals that it also requires the "Recipient Management" or "Security Administrator" roles.

You can add users to role groups  in EAC- Admin roles.
