Relay Mail Failed

Hello,

We are using SMTP Relay Settings in ZOHO CRM for sending emails using office 365 server. But every time we are receiving below errors.

The Relay Configuration for the domain Domain.com and feature WorkFlow has failed 3 times today . Mails will be sent through the Zoho CRM server until next day instead of configured relay.
