You can now connect Outlook Mail, Outlook Calendar, OneDrive, SharePoint and Microsoft Teams from Connections, each with your own Microsoft sign-in. Your bots can then read, file and send your mail, manage your calendar, work with your files and SharePoint sites, and read and post in your Teams chats and channels, as you. Outlook and OneDrive work with personal Microsoft accounts too, while SharePoint and Teams need a work or school account.
Most work and school organizations have an IT admin approve Emra once before anyone there can connect. If yours does, the sign-in shows a note and a link to send them.
