Resource Calendar - licenses & Modern Auth

Exchange (Office365) has the option to create "resource" calendars, which do not require a user license.

You can create a bunch of these and use just one user login to connect them to Concierge (using the "Connector resource address" field).

One thing you might come across is if people have a "Teams room" with Video Conferencing set up. In that case the room does need a license (to use Teams), but Concierge connects to it in the same way.

Modern Auth

Please leave Connector address, username and password blank.

Connector type will be 'Microsoft'

Connector resource address will be your mailbox SMTP address, if you have one (screenshot below).
