what is ews url

EWS URL stands for Exchange Web Services URL, which is the address of an Exchange server that is required for integrating with Exchange/Outlook Calendar. The EWS URL has a special format: https://<mail-server>/ews/exchange.asmx, where <mail-server> needs to be replaced with the address of the Exchange server. The EWS URL is usually auto-detected using the email address, but sometimes the auto-detection may fail, especially if the Exchange admin disabled auto-detection. In such cases, the first user of the account connecting to Exchange will need to provide the EWS URL. There are several ways to obtain the EWS URL, including logging into the mailbox via the browser and copying the server address or the entire URL, using PowerShell on the Exchange server, or using a tool like Microsoft Remote Connectivity Analyzer. Once obtained, the EWS URL can be inserted into the appropriate field in the integration settings.
