(Updated) Viva Engage: Email updates for frontline users without an active Exchange mailbox

🚨 The Signal: Viva Engage will stop sending email notifications to frontline users (F1/F3 licenses) without active Exchange mailboxes. This reduces email system load and improves delivery reliability for critical communications by eliminating retries to non-existent mailboxes.

The Impact

Frontline users with F1/F3 licenses and no Exchange mailbox will no longer receive Viva Engage emails, posing a low security risk.

• Frontline users: May miss Viva Engage email notifications if they lack an Exchange mailbox.
• M365 Admins: Reduced email gateway load and improved delivery efficiency for other communications.
• Security Teams: No direct security risk, but awareness of communication channel changes is prudent.
