Outlook / Microsoft Calendar Integration

Connecting your Microsoft Outlook Calendar to QuantixOne works the same way as Google Calendar — appointments booked through QuantixOne are added to your Outlook calendar automatically, and events you create in Outlook block your availability on the QuantixOne booking page.


Connecting Your Microsoft Account

From the Calendar section, click the Settings dropdown in the top navigation and select Connections.

On the My Connections page, click Connect on the Microsoft Outlook card.

A Microsoft sign-in window will appear. Log in with your Microsoft or Outlook account, then grant QuantixOne permission to access your calendar.

Once authorised, your Microsoft account appears in the connected accounts table with a Connected status.

Setting a Primary Microsoft Account

If you have connected multiple Microsoft accounts, click Set Primary next to the account you want to use for syncing new appointments.

Note: Only one Microsoft account can be set as primary at a time.


How Sync Works

  • QuantixOne → Outlook — New appointments created in QuantixOne automatically appear as events in your Outlook calendar. Rescheduled or cancelled appointments update or remove the corresponding Outlook event.
  • Outlook → QuantixOne — Events you create directly in Outlook are detected and block those time slots on your QuantixOne booking page so clients cannot double-book.

Syncing a Specific Calendar to a Specific Connection

To sync a specific calendar to a specific Microsoft account, set that account as Primary. QuantixOne will use the primary account when syncing appointments for that calendar.

Note: Only the primary Microsoft account is used for syncing. To change which account a calendar syncs to, update which account is set as primary.


Disconnecting Microsoft Calendar

To remove the integration, go to Settings → Connections, find the account in the connected accounts table, and click Disconnect.

Note: Once disconnected, your Outlook events will no longer block time on the booking page. Reconnect the account whenever you want sync to resume.
