Riva Cloud connects to Microsoft Exchange by using Exchange Web Services (EWS).
By default, EWS is installed and is hosted on the same server as the Outlook Web Access server (CAS).
This is the same host and service that is required to support Apple Mail, Entourage 2008 for Mac, and Office 2011 for Mac.
To create the EWS connection:
Riva Cloud must be able to connect to your Exchange Web Services server from the internet.
If Riva Cloud reports that the connection was not successful, contact your Exchange administrator (or hosted Exchange service provider) to confirm the following:
Riva Cloud uses Exchange Delegate Access mode to access target user mailboxes. If the Riva connection user in Exchange was configured with Exchange impersonation access, you will see access errors when attempting to sync data to or from Exchange.
To correct these errors, contact the Riva Success Team, and ask to have the impersonation method set to Exchange Impersonation on the EWS connection.
