How to add Exchange calendar on macOS

  1. Requirements

    The Exchange connection can be used for syncing your Exchange or Office 365 calendars. If you are having problems you can ask your system administrator if these requirements are met:

    • Exchange 2007 or higher.
    • Exchange Webservices must be installed and configured.
    • Multi factor authentication and modern authentication are not supported.

  2. Install OneCalendar

    Download OneCalendar from the store and install it on your device.

  3. Select Accounts overview

    Select the OneCalendar menu on the top left, and select the option "Accounts".

  4. Select Add account

    Click on the "+" sign to add a new account.

  5. Select Account type

    Click on the "Exchange" account type.

  6. Enter credentials

    OneCalendar will try to autodetect your settings. This will not always work. If it fails, the following screen will be shown.

    • Enter server. This should be the URL to the Exchange Webservice (EWS). You can ask your system administrator for the correct URL. It will be similiar to your Outlook Web Access (OWA) URL. It will be something like: https://yourserver.com/EWS/Exchange.aspx
    • Enter the domain name of your company (optional)
    • Enter the user name which you use to log in to your company's computer
