This FAQ will give instructions on how to determine the EWS URL and configuring it for Quicklaunch. A common cause of authentication failures when configuring the Exchange connector to work with Exchange Web Services (EWS) is using the incorrect URL.
1) Receive EWS URL for Microsoft Office 365
2) Receive EWS URL for on-premises Microsoft Exchange Server (Amin Only)
3) Receive EWS URL without browser
1) Microsoft Office 365
Once logged in, select the Settings Gear Icon on the top right, and select "View all Outlook Settings". Then select the following: Settings > Mail > Sync Email
The URL of exchange web service for the mailbox is the URL: https://<mail.server>/ews/exchange.asmx
2) EWS URL for on-premises Microsoft Exchange Server (Amin Only)
The default URL for EWS is https://<mail.server>/ews/exchange.asmx
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
3) EWS URL without using an internet browser
If you cannot access your email account via the browser, use this tool by Microsoft to discover your EWS URL: Microsoft Remote Connectivity Analyzer.
For Auto Discovery, any valid email address can be used, it is recommended to use the email address of the user in the Protocol tab.
The email address is used for two purposes: the right part after "@" character (the domain name) is used to locate the Auto Discovery service when the connector is used outside of Windows domain. (Within a domain system, the Auto Discovery service location is fetched from the Active Directory) When Auto Discovery service is located, the entire email addresses sent to the service, and the service estimates the best (optimal) EWS service URL which can be used to access the mailbox of the user. So when there are multiply EWS entry points in the system, you should choose an appropriate email address for access every entry point (this means you have to create at least one connector profile per entry points - you can do that based on structure of organization of the user company).
