This article describes how to prepare for a Riva connection to Exchange on-premises using Exchange Web Services (EWS).
Riva On-Premise supports connections to hosted and on-premises Exchange systems. If your Riva On-Premise server is not connecting to on-premises Exchange using EWS, refer to one of the following:
Supported on-premises Exchange systems: Riva uses Exchange Web Services to connect to the following on-premises Exchange systems:
To prepare to connect to on-premises Exchange
A connection to Exchange is established by Riva using the configured credentials of an Exchange "service user" that has been assigned permissions to access the mailboxes that will be processed.
For more information, see How does Riva communicate with Exchange?.
The Exchange service user used by Riva is referred to as the Riva connection user.
To prepare the Riva connection user:
The following steps are recommended if using "Delegate Full Access" permissions:

This is typically the same infrastructure used to host the Outlook Web Access and the ActiveSync mobile devices services. Also Mac-based Outlook and Mail apps also leverage the same EWS sub-system to be able to access the end-user's mailbox content.
However, it is always recommended to confirm that both Windows and corporate firewalls are configured to allow the Windows server used to host the Riva processes access to the server that is responsible for Exchange EWS (ports 80 and 443). See Firewall settings for Riva.
On the Windows system that will host the Riva On-Premise server, confirm that you can log into the Outlook Web Access using the Exchange service user account login credentials. Outlook does not need to be installed on this server.
Ensure that each user mailbox that Riva will sync is ready:
