Astalty Premium - This feature is part of the Astalty Premium plan. See What Premium includes.

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.

> **Always edit integration events in Astalty**
>
> For an event created in Astalty, Astalty remains the source record. Edit or delete that event in Astalty so the change is sent to Outlook. Editing or deleting only the Outlook copy does not update the Astalty record.

## 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](https://docs.astalty.com.au/guide/calendar/calendar-set-up/connecting-your-outlook-calendar)**.

Once connected, see **[Creating an event using the Outlook Calendar integration](https://docs.astalty.com.au/guide/calendar/using-the-calendar/creating-an-event-using-the-outlook-calendar-integration)** to start scheduling.

If an Astalty event or its latest changes do not reach Outlook, open the event and follow [Sending a Failed Event Again](https://docs.astalty.com.au/guide/calendar/using-the-calendar/calendar-events-and-tasks#sending-a-failed-event-again). The event warning explains whether to reconnect first or whether a partly synced repeating series must be deleted and created again.

## 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.
