So far base on my knowledge you are trying to set up Zoom and you need the EWS URL found in EMC/ECP.

1. In the Exchange Admin Center, click servers.
2. Click Virtual Directories, then double-click EWS.

3-Click General, and locate the EWS URL.

Once you find the EWS virtual directory, the URL should be displayed there. It typically starts with "https://" and includes the server's name or IP address, followed by "/EWS" or a similar path.

Please note that the exact steps and terminology may differ depending on the version of Exchange you are using. If you're unsure or unable to locate the EWS URL, it may be helpful to consult your organization's IT support or Microsoft's official documentation for your specific Exchange version.

The default URL for EWS is **https:///ews/exchange.asmx(often this may be the same server that OWA is hosted on

If using the above URL with the appropriate domain is not functional, the correct URL can be retrieved in one of 2 ways:

1. The Exchange admin can use a PowerShell command on the exchange server

a. Open PowerShell on the Exchange server

b. Type Get-WebServicesVirtualDirectory |Select name, *url* | fl

c. The URL will be provided
