Calendar with Gnome
GNOME Evolution is an open-source email client for Linux and is written in the C (GTK) programming language. The official description from its website says, "Evolution is a personal information management application that provides integrated mail, calendaring and address book functionality." We use the test@dynu.biz email account as an example in this tutorial.
After launching the email client and adding your email account, go to Settings, then click on the Online Accounts button and choose Calendar, Contacts and Files.

Use the below settings:
- Server Address: https://collaboration.dynu.com
- Username: Your email account username. In our case, test@dynu.biz.
- Password: Your email account password.

You see a window with the propagated server address and then go away on its own.

To complete the setup, be sure to uncheck the Files option.

When opening the calendar, you may be prompted to enter the username and password again. Be sure to Add this password to your keyring.

Once you have the calendar ready, you can click on a date to create a meeting. Be sure to add the event under your Dynu online calendar instead of a local one. Once an event is added, it will show up on the calendar.


You can manually synchronize the calendar from the calendar dropdown with the Synchronize Calendars option.
