Zoom for Outlook can't "access Zoom"

[Chris_C_CA]

I installed and connected the Zoom for Outlook add-in on my Mac. The add-in, Zoom desktop software, and my MacOS are all updated. When I add a calendar event in the desktop Outlook app, Zoom appears in the toolbar, but when I click Zoom > "Add a Zoom meeting", I get the "Adding Zoom Meeting..." pop-up, a circle spins for a minute, and then an error: We're sorry, we couldn't access Zoom. Make sure you have a network connection. If the problem continues, please try again later."  Notably, if I switch over to the Zoom app calendar, I can see an event created there with a Zoom link (it just does not successfully transmit that data back to the Outlook Calendar event).

The Zoom add in does work if using Outlook on the web. My internet connection is otherwise fine. Any ideas? I have tried un-installing and reinstalling both the Zoom desktop app and the Zoom for Outlook add-in several times with no results. Running MacOS Tahoe.
