Hi every one i have a problem to get access list members In Shared Mailboxes office 365 using Unified API.
i\'m using this endpoint API https://graph.microsoft.com
Office 365 Unified API doesn't yet support access to shared mailbox content or membership. Access to content is on our roadmap, and something we hope to enable before the end of the year. We are looking at membership as well, but have no firm plans.
