Outlook Calendar (v3.14)

Connect your Microsoft 365 or Outlook.com calendar, next to the existing Google Calendar option.

Meeting reminders:
the desktop and mobile apps remind you when a meeting starts. You can also connect from the web app.
Meeting context:
the meeting title, attendees, time and Teams link come into the session as context, including sessions you start from a reminder.
Where:
Settings → Automation & Data → Connect Outlook Calendar.
Work accounts:
if your organisation requires an administrator to approve apps, Hedy shows what to send them, with a link you can copy.

One calendar can be connected at a time. Outlook doesn't share the invite's description, so there is no agenda from Outlook invites.
