I'm using Outlook desktop client connected to my CalDAV calendar and I can't see SimplyMeet.me meetings

From SimplyMeet.me

Outlook desktop client treats the timezones of the CalDAV's events in a different way. At the moment it won't be possible to display SimplyMeet.me meetings in the Outlook desktop client, although your meetings will be still visible in your CalDAV calendar.

A temporary solution is to use the eM Client instead of Outlook desktop client.
