Ensure MailTips are enabled for end users
Why This Matters
Without MailTips enabled, users lack proactive warnings about potential issues when composing emails, such as accidentally sending to large distribution groups or external recipients outside your tenant. This increases the risk of data leaks, unwanted external communications, and non-delivery reports that disrupt workflow. Enabling MailTips gives administrators a cost-free mechanism to reduce human error and improve email hygiene across the organization.
What Aether365 Checks
Aether365 verifies that the MailTips feature is enabled at the organization level in Exchange Online. This appears in the Aether365 dashboard under Microsoft 365 checks and reports non-compliance if any of the required MailTips settings are not configured correctly.
