I'm looking for an easy way to quickly update (and keep up to date) the Manager - Direct Reports data in Exchange Online. Right now, the only way I have is to go into EAC and manually update one user at a time. I'd also like to find the best way to keep the relationship up to date once we get everyone updated.
Clarification As far as "keeping the relationship up to date," I was thinking of either pulling the information from some other source on a schedule or giving a non-technical HR employee a way to make the change directly.
