O365 Accepted domains shows Authoritative and needs to be Internal Relay but grayed out

Hello EE,
Users cannot email our .eu office and I found it is because the domain is listed as Authoritative under Admin > Mail Flow > Accepted Domains and it's grayed out so I can't change but I need it to be internal relay.  Please help.

Yes,

Authoritative Accepted Domains uses:

whenever a user receive any email which is belongs to this same Authoritative domain. It comes like this.

From remote (Gmail or any) domain >> then it will go to Exchange >> then Exchange will query to AD whether the user is listed or not.  AD replies the user is not their in my list.
Exchange will generate DSN which means, NDR.

Suggestion, first of all delete that and recreate a new one make sure select internal relay option.

Otherwise stopped MS Transport service and make the changes.

Thank You!

@James: Tried that but getting: A positional parameter cannot be found that accepts argument -DomainType

@Mohd I cannot delete as it says some users are using it.  Plus just added a test and don't have an option through the web to pick internal relay.  If I stop MS Transport service where can I make the change in the web interface will it not be greyed out?
