Omni.Scheduling.SchedulePostponeException: The remote name could not be resolved: 'bogus' ---> System.Net.WebException: The remote name could not be resolved: 'bogus'
Cause
Closer examination of the network environment revealed that there is a proxy environment (named "bogus") using AD authentication credentials to grant network access. The user was logged into Windows using an AD admin level user, but the Riva connection agent service was configured to log on as the LOCAL SYSTEM user.
When the user ran the connection tests from the Riva Manager application, Windows used the credentials of the logged-on user. When the Riva connection agent service tried to connect to Exchange, LOCAL SYSTEM was not authorized for proxy access, and a result, it was unable to resolve the name of the EXCHANGE system configured in the Riva connection.
Solution
Configured the Omni Riva CRM Agent service to log on as an AD user with administrator or super-user equivalent permissions, and the proxy granted network access.
