LEM "Email Active Response" connector does not work when using Microsoft Exchange Virtual IP (VIP)


Solution 1:

Change LEM Email Active Response connector settings for Mail Host to reflect the Exchange physical IP address instead of the VIP previously configured.

Solution 2:

Clear the contents for Authentication Server UN and Password fields in the Email active response connector and save and start the connector. Test email delivery using the blue envelope.
