When launched in 2015, Outlook groups were an email-based collaboration platform. Now called Microsoft 365 Groups, the few Outlook groups that host email-based discussions have a distinctive Graph API to create and manage the conversations, topics, and posts which make up their discussions. This article reviews how to fetch these objects and how to create new conversations and reply to posts (using the Outlook Groups APIs, of course).
Outlook Groups now boast support for folders and rules. In other words, group owners and members (if allowed) can create new folders and move and copy items from the inbox to those folders. They can also create rules to process inbound email arriving into the group inbox. It’s all well and good, but there are a few points to understand about how things work.
It might seem like a small thing, but some users are upset when they don’t receive copies of their messages sent to Outlook Groups in their Inbox. A new setting allows users and administrators to control if they receive copies of messages from groups, but only when the user is a subscriber to groups (Follow in Inbox is turned on). In this article, we explore how to set the EchoGroupMessageBackToSubscribedSender control via OWA options and PowerShell, and how to sign up to be a group subscriber by yourself or with a little help from an Exchange administrator.
