@Mykle1, yes the out of the box calendar works. Im trying to understand what I did wrong with mine.
If anyone did do it this way pls let me know. My work office 365 calendar cannot be published online, and sharing options also dosnt work, the only opiton I could find is via webcal

Mykle1, thanks i did as you said, however now it says no upcoming events. (there are few).

Thank you Sean, indeed, after I’ve added a comma the error disappeared and mirror loaded, however, the Calendar module says Loading…
Do you, or anybody knows how I could troubleshoot this? Did anybody do something like this?

Thank you in advance for help!

Hi Gents,
I’m a recent Magic Mirror enthusiast, needless to say complete noob in the coding. I’ve managed to install the MagicMirror (thanks for detailed guidelines) and even added Weather and News module, however struggling with my Calendar.
I would like to add my work Office 365 Calendar events, to the MagicMirror. I’ve published it at the email server that supports webdav. Now, Im trying to add the code in to the config file, and it says that config is broken. I assume I made some syntax mistake I cannot see, and other thing is im doing this correctly? (Office 365 > webdav)

 {
            module: "calendar",
            header: "Events",
            position: "top_left",
            config: {
                calendars: [
                    {
                        symbol: "calendar-check-o ",
                        url: "webcals://webdav.yandex.ru./My_Calendar.ics"
                            auth: {
                user: 'xxx@xxxx.xx',
                pass: 'xxx',
                method: 'basic'
                    }
                    }
                ]
            }
        },
