Additional context for the security justification: Abuse of the email service by compromised credentials is a very large and growing issue. These credentials are used to access mailboxes, send out phishing to other people, and potentially exfiltrate sensitive email messages. 
  • Disabling unnecessary protocol access to accounts makes it more difficult for malicious actors to automatically test the validity of passwords obtained from phishing and 3rd party password database dumps.
  • Reducing the number of protocols that can be used to export data from a mailbox will help reduce the risk of data exfiltration due to abuse via compromised credentials.
  • If (and when) Multi-Factor Authentication (MFA) is available and enabled for an account, disabling these non-legacy protocols is a way to ensure that malicious actors can’t bypass MFA by using a legacy protocol that isn’t compatible with MFA.
