Outlook Calendar

The Outlook Calendar integration displays selected Microsoft calendars in Astalty and sends Astalty events to one selected main Outlook calendar. It is a per-user connection and requires access to the Astalty Calendar.

What It Does

• View existing Outlook Calendar events inside the Astalty Calendar.
• Send events created in Astalty to the connected user's main Outlook calendar.
• Update or delete the Outlook copy when the connected user updates or deletes its Astalty event.
• Create Microsoft Teams meetings and invite attendees from an Astalty event when the main calendar supports meetings.

How It Works

Each user connects their own Microsoft account. Astalty lists only external calendars belonging to that user's connection, and the user chooses which calendars are enabled for display. Existing Outlook events are read from those calendars when Astalty loads the selected date range. Changes made to those external events in Outlook are therefore reflected when Astalty fetches them again.

Connecting It

Each user connects Outlook Calendar from their own My Profile > Integrations tab:

1. Under Microsoft Integration, select Connect and complete Microsoft's authorisation flow. Your Microsoft administrator may need to approve the app for your organisation.
2. Open the user's Calendar tab. Astalty syncs the available Microsoft calendars for that connection.
3. Select Manage, tick the calendars to display under Enabled Calendars, and choose an editable calendar as Main External Calendar.
4. Select Update.

Only enabled calendars appear in the Astalty Calendar. Events created in Astalty are sent only to the main external calendar. Without a main calendar, Astalty warns that outbound events, attendee invitations and video calls are unavailable.

If Microsoft Integration is missing, confirm the user has Calendar access. For the full connection walkthrough, see Connecting your Outlook Calendar.

Once connected, see Creating an event using the Outlook Calendar integration to start scheduling.

Disconnecting or Reconnecting

Open My Profile > Integrations. Select Disconnect on the Microsoft Integration card to stop displaying its calendars and stop sending new Astalty events to Outlook. If the card shows Invalid, select Reconnect and complete authorisation again rather than disconnecting the connection.
