Exchange Online/EOP or Exchange Transport Rules & Distribution Groups
“The transport rule can’t be created because Group@domain.com, the recipient to be added by a rule action, is a distribution group. Transport rules can’t add distribution groups to messages. To resolve this error, remove this recipient and specify a different one”
- Create Shared Mailbox or Mail Contact & Enable forwarding to Distribution Group.
- Post which you can apply Shared Mailbox to replace Distribution Groups.
This may not work in Exchange as well, In that case the workaround is to use the message header match:
- Create using AnyOfToCcHeader
- Set the preferred action
