Office 365 mail Delivery Management for Distribution Group

Hi there,

I have a Distribution Group where the Delivery Management is set to internal only.

I need to allow only one external sender to be allowed to send to this DG. When I change the delivery to inside and outside I can add all my internal users but I am not able to add the external email.

Does anyone has an idea how to allow the external sender to send to the DG?

Thanks

Hey bro,

You don't need to find allowing external access permission.

In EAC, edit O365 group, in membership, add that external account - like the MS guy mentioned adding it as guest user first, then that account will be able to added. It will be definitly work~
