How to use Roundcube Calendars

All Anu Hosted Email accounts include Roundcube Webmail. Roundcube allows you to send and receive email via your browser with no additional software or configuration required.

If you want to set up a shared calendar, click on the small + sign (see screenshot). Once you clicked on the button, it will provide you 2 options, either “Create a calendar” or “Add shared calendar”.

If you want to choose to create a calendar, it will open a form with tabs to configure the details (Summary, Share Calendar, Publish Calendar, Sync Calendar and Import/Export).

Summary tab – It will ask your for the Calendar name, Description, Background color, Text Color and Default Event visibility which gives you 2 options either private or public.

Share Calendar tab – This is where you want to share your calendar and you will be asked for the email addresses of the users that you want to share your calendar to.

Publish Calendar tab – This is where you can share your calendar publicly without inviting the users so anyone that has the link will be able to view your calendar. Normally if you are creating the calendar this option will ask you to create the link first before you can share it to public.

Sync Calendar tab – This is where CalDav connection is set. It will ask you for the Display name, Password, Either you want it on a read only mode or shared.
