I have had a few requests for this and have not been able to produce so im turning to some experts:
We have a distribution list called "all companies". In this list are more distribution lists named "all boston staff", "all New Yrok Staff" etc. I need a way to export to a csv, all of the members of the "all companies" distribution list that has all of the members of the child lists. I know this can be done in powershell but every port I have found has fallen flat, given an error or other.
We are using office365 and not an on premise exchange solution.
Thanks in advance.
