Hello together

In one of the newer beta versions there is now a first approach where every user can create a group by himself. But this group is not domain spanning and available for all users. Currently, as far as I know, each user has to maintain such a list by himself.

What is the roadmap here? Is this a feature we can expect soon?

I think we need more detail.   I have worked with earlier versions of Exchange and I don't understand your objection.   

For lists created manually by the domain administrator, Exchange distribution lists seem equivalent to SmarterMail alias names.   

For lists created manually by an individual user, the group name may be usable as a To address but I don't believe it is valid for replies.   Outlook with SmarterMail should be able to do the same thing.

You seem to want something automated.   Are you indicating that Exchange allows a Distribution List to be populated by an Active Directory group, and SM should do the same?

Yes but the difference is that in SmarterMail you have to enter the email address line by line for an alias, I don't see that as practical and in Exchange you don't have to do that either but you add the user to the group so that he is a member of it and that completes the list. For a few emails in an alias no problem but as written in my first post this is no longer manageable if you have a lot of subscribers.

I wish in SmarterMail that you can select the users for such a distribution group or ideally select and enter them based on the newly added group properties.
