Unable to add Shared Exchange Calendars from Exchange

[jkundi]

Hi all, I'm trying to add a shared calendar from my work Microsoft Exchange account to the default Mac OS Calendar. I've added my account and can see my default work Calendar appear as normal.

However when I try to access the shared Calendars via the delegations option, I'm getting an error which states no Calendar can be found on the server. I'm finding this strange as this is working flawlessly on my iPhone using the default Calendar app. Anyone else experienced this problem on Mac OS?

I tried another Calendar app called Fantastical and it is able to find the shared calendars perfectly. However I'm trying to stay away from a premium app.

Thanks
Jas

Whoops. Maybe re-adding the account could help?
Those Calendars main func. should be versal. Creation of event transmission is a wits end.

Does your work servers require authentication? Monterey appears to have broken Calendars interacting with authenticated servers and don't display an authentication input screen (both my 2019 Mac Pro and 2015 MacBook Pro with latest Monterey no longer work) to validate the device to the server. When I hop onto my 2012 Mac Pro running Mojave, its Calendar application correctly displays the authentication input window when I add my work account. I've reported this to Apple about two months ago but no resolution in sight.
