O365 - Trying to create the equivalent of a Dl which will contain just external email address.
Can't use a DL or 0365 Group as I would then have to create a contact in O365 for each external email address.
I have one DL setup with external emails address and I did it by creating a user (which of course needs an O365 Licences) and with in the account, under contacts setup a group, which I was then able to add external email address to, without having to setup a contact for that external email address.
So other users in the organisation can add/delete/edit the list of email address in that list, I added a security group to the contact group. (Hope that all makes sense)
Trying to determine if there is a better way to do this.
