Allow group owners to self-serve delivery management options

Question

In our exchange, users have the ability to create their own mail distribution lists using the exchange admin centre UI. As part of doing so, they can assign themselves and others as owners of the group.

By default, the distribution list is set to 'only allow senders inside my organisation', therefore any mail from external addresses is rejected. We want the owners of the group to be able to self-serve this and amend the setting, but under delivery management this is what they see - they don't have the option to change and are instead directed to contact an exchange admin.

If signed in using an admin account, they see the options we require and are able to amend the group so that 'senders inside and outside the organisation' are allowed'

Is there an exchange configuration setting that can control this behaviour? Our requirements are - group owners should be able to change delivery management to 'senders inside and outside the organisation' without requiring an exchange admin account.

Answer 1

No that would allow them to do this globally. However, if they have the ability to create DLs in the Admin Center now, they already have pretty powerful permissions.
There is no way to limit only owners to manage their own DLs this way unless you set up some pretty consulted RBAC permissions and maintained a list of each DL owner and even then it prob wouldnt really work the way the want.

Note: Office 365 Groups in Exchange Online do offer this ability however!

Answer 2

What role did you assign them to let them create their own DLs in the Admin Center?

If you create custom role and assign the Distribution Groups role to a set of users, then they should be able to manage them completely
You can do this under:
