No matter what changes I make. It seems like all of my Auth0 outbound emails are going into quarantine for Office365 users. Sendgrid and Mandrill will both show the mail as delivered but it gets stopped at the Office365 server and sent to quarantine for “High Confidence Phishing”
Even using default Auth0 email templates and different email providers(sendgrid and mandrill). Emails are going into quarantine for what seems like only office 365 users. I could be wrong though.
Ive reached out to microsoft to help me pinpoint why. But they were unable to provide me with much assistance.
Can anyone point me in the right direction or provide any advice?
