Send-as and Send-on-behalf of for groups in Outlook
Yup, the messaging is confusing (we can blame marketing talk), this has been around for a while. And no, you cannot use O365 groups to delegate access to all members of the group, they are still not recognized as valid recipient for that task. Mail enabled security groups do the trick though :)

Hi, Not sure i understand your question completely, can you please clarify what you eman when you say you are trying to use a Group to send to on-prem DL?
Groups are in cloud - correct, and in a Hybrid environment, they will be written back to the on-prem side of the fence as a DL only if the tenant has AAD premium enabled with 'write-back' on. This capability to write back groups to the on-prem GAL is done by AAD Connect write back feature. Lack of this, on-prem users in Hybrid environment will not be able to view and resolve this group in their GAL.
If you are looking to upgrade your on-prem DLs to Groups, we'd be happy to help you with this. Please let us know
