We are happy that O356/Outlook.com has been added to our list of Calendar integrations which already includes Google, Zoho and Zoho CRM.

The integration is a two-way sync leaving no chance for a double booking. 

O356/Outlook.com calendar integration is available in all plans including the Free plan. 

To access the integration, go to the 'Manage Business' page. Under 'Integrations' tab on the left hand pane, you will see 'Calendars' and on that page you can enable 'O365/Outlook.com'.

Please read more about this integration and how to enable it here.

As always, try the feature and let us know your feedback and improvement requests.
