Is this summary helpful?
We’re making some changes to the migration from classic Outlook to new Outlook for Windows.
Starting January 6, 2025, and over the following months users with Microsoft 365 for Business Standard and Premium licenses will be toggled from classic Outlook for Windows to new Outlook for Windows. Users will be toggled into new Outlook only once with this roll-out, with potential to be toggled again in the future. Users will maintain the ability to go back to and use classic Outlook.
Our goal with this change is to give users an opportunity to try new Outlook as millions of users already have. New Outlook gives users the most modern experience with Copilot features, theming, and a wave of valuable time-saving features like Pinning and Snoozing mails. Users are also welcome to give us feedback on new Outlook using Feedback in the Help ribbon, so we can tailor the best email and calendar experience.
When this will happen:
General Availability (Worldwide): We will begin rolling out January 6, 2025.
How this will affect your organization:
You are receiving this message because our reporting indicates one or more users in your organization are using Microsoft 365 Business Standard or Business Premium.
Users will have notice in the application prior to being toggled and will have the option to turn it off in Outlook Options > General. Users who are toggled into new Outlook can toggle back to classic Outlook if they choose to.
Users will not be toggled if one or more of the following is true:
New Outlook toggle is hidden via policy
Perpetual license is in use
