Can't connect to my exchange server

[BWM2024]

I've used zoom and had it connected to my outlook email server account for years.  A few weeks ago we received a message that it was not connected to the email server and we couldn't schedule meetings in my calendar anymore.   I don't believe it's ever asked for this EWS server before, but we input the EWS server exactly as we were told by our tech support and I'm still getting the same error message.    Any idea what I may be doing wrong?

Error: Zoom could not log into the calendar service account.

If your Exchange server is undiscoverable from the internet, you can also input your calendar resource (your email address) to sync up your calendar.
