Manage all aspects of plain old Distribution Lists (NOT Office 365 Groups).
We have the need to create Distribution Lists in Exchange, NOT Office 365 Groups, as we do NOT need all the overhead associated with the Office 365 groups. We simply need the Distribution Lists to collect a group of email addresses and treat them as a single unit. We don't need them to log in, we don't want to provide them with a running history of email conversations and we don't want them to get a "welcome" email message. We just want to send an email to a single email address and have it be disbursed to the addresses on the list.
I need to manage the Distribution Lists in an automated way via a custom program Graph doesn't look to allow me to manage lists.
Additionally, I need to be able to create Mail Contacts (again NOT Office 365 Users) and assign them to the groups.
Having the ability to add members to a distribution list would really help! We have no interest in using Office 365 Groups as it is complicated to add external recipients. It is so much easier to add an external member to a distribution list via the Admin center. Would like to be able to do this via Microsoft Graph.
