Microsoft Users: Prepare for Automatic Switch to New Outlook

Starting January 2025, Microsoft will begin automatically switching users of classic Outlook to the new version. This change will primarily impact Microsoft 365 Business Standard and Premium users, with updates for Enterprise users planned for April 2026.

Key points to note:

• The switch will occur gradually over several months, beginning in January 2025.
• Users will receive in-app notifications before the automatic switch.
• IT Admins can opt out of the automatic switch if not ready for the transition. Instructions for opting out are available here.
• After the switch, users can still toggle back to classic Outlook if needed, but they might automatically be switched to the new Outlook again with a future rollout. Instructions to toggle back are available here.
• Microsoft will support existing installations of classic Outlook through perpetual licenses until at least 2029.

We recommend familiarizing yourself with the new Outlook features, including the new interface and productivity tools, and preparing your team for this transition.
