Owing to the new Microsoft Exchange DMARC Policy Handling update (https://techcommunity.microsoft.com/t5/exchange-team-blog/announcing-new-dmarc-policy-handling-defaults-for-enhanced-email/ba-p/3878883), we recommend all customers using MS Exchange mail server to authenticate your domains in Apptio Targetprocess email provider (Sendgrid).

For further assistance, please contact our support team at firstname.lastname@example.org. In your email, add the domain name to authenticate so that we can expedite the help process. Our support team will make the necessary changes in email provider settings. However, you will have to add DNS records on your domain side to verify this authentication.
