Unable to allow shared mailbox to send to distribution list in delivery restrictions

Currently hybrid Exchange 2013, migrating to cloud with EX2019 on-prem management.

Why can I not allow a shared mailbox to email a restricted distribution group? It even allows contacts to be added?

Hi @AlistairNelson-1385

Agree with the reply above from michev, try using powershell to add the shared mailbox to the allowed sender list

using the parameter -AcceptMessagesOnlyFromSendersOrMembers in the command Set-DistributionGroup

I tried in my environment, I perform the operation in Exchange online side, seems that in classic EAC, shared mailbox is not visiable in the list, when I change it to new EAC, we are able to choose them there. If the changes need to be made on-prem, like we discussed above, use powershell to meet this need.

I suppose you are using the UI, the list of objects presented there might be limited in some cases. Just add it via PowerShell.
