We have announced that Group Owners will be able to leverage existing groups to drive membership in Office 365 Groups.Carl commented
Will i then be able to populate a dynamic o365 security group using an LDAP attribute and then use that dynamic security group to populate o365 groups and shared mailboxes?
For example. Out identity management system automatically populate the LDAP attribute City depending on location. I then want O365 to use that city attribute to automatically assign those users to the corresponding Team, Distribution group and Shared mailbox.
I can do this today with a dynamic O365 group but not afaik with Shared mailboxes.
