Have you tried using the SynchronizingRolesSecurityEntityProvider ?

Alright, so the class you mentioned has a function FindUsersInRoleAsync, and it returns a Tuple<IEnumerable<string>, int>, where IEnumerable<string> is a list of usernames. 

_notifier.PostNotificationAsync(new NotificationMessage()
                {
                    ChannelName = "SlettingAvBlokk",
                    Content = content,
                    Subject = "Ansattblokk slettet",
                    Recipients = receivers,
                    Sender = sender,
                    TypeName = "PageChanged"

}).GetAwaiter().GetResult();

The method expects Recipients to be an IEnumerable<INotificationUser>. How can we get INotificationUser-objects from a list of usernames? Can we call the method FindAsync in the class QueryableNotificationUserService to retrieve INotificationUsers, or would that not work since users are logging in with Azure AD?

Hi Tam

You can create the NotificationUser objects as follows, and pass to the PostNotificationAsync method

 var users = await _synchronizingRolesSecurityEntityProvider.FindUsersInRoleAsync("WebAdmins", null);
 var notificationRecipients = users.Select(u => new NotificationUser(u));

I believe the Notification Dispatcher Job will resolve the users when sending the emails. Give it a go
