Microsoft Outlook: Updated behavior for switching back from new Outlook to classic Outlook for Windows [MC1066342]

Message ID: MC1066342

Coming soon: We will change how users switch back from new Microsoft Outlook to classic Outlook for Windows to make it easier for users to simultaneously use classic Outlook and new Outlook.

[When this will happen:]

General Availability (Worldwide, GCC): We will begin rolling out the default behavior to keep new Outlook minimized after a user switches out of new Outlook in mid-May 2025 and expect to complete by late May 2025.

General Availability (Worldwide, GCC): We will begin rolling out an option to open classic Outlook without switching out of new Outlook in early June 2025 and expect to complete by late July 2025.

[How this will affect your organization:]

Before this rollout, if users switch from classic Outlook to new Outlook, they must switch back to use classic Outlook again.

After this rollout, users will be able to use classic Outlook without switching out of new Outlook. When users select the toggle in new Outlook, they will have the option to open classic Outlook or switch back to classic Outlook.

If users choose to open classic Outlook, it will launch right away without requiring the user to switch back. Learn more: Switch to new Outlook for Windows – Microsoft Support.
If users choose to switch back to classic Outlook, new Outlook will be minimized in the taskbar and classic Outlook will launch, allowing users to seamlessly use both apps. New Outlook notifications and reminders will be suppressed for that session and classic Outlook notifications will be shown.

This change will be on by default and will not change existing settings or defaults for your organization.

[What you need to do to prepare:]

This rollout will happen automatically by the specified dates with no admin action required before the rollout. Review your current configuration to assess the impact on your organization. You may want to notify your users about this change and update any relevant documentation.

The upcoming update to Microsoft Outlook is set to bring some exciting changes for both administrators and users alike! With the ability to switch seamlessly between new Outlook and classic Outlook, we can expect a smoother workflow and increased productivity.

For users, this means no more fumbling around with the taskbar to switch back and forth. Instead, they can keep new Outlook minimized while accessing classic Outlook when needed. Imagine the convenience of having both applications at your fingertips without the hassle! It’s like having your cake and eating it too—who doesn’t love that?

Admins will appreciate that this rollout requires no action on their part. The update will happen automatically, allowing them to focus on other important tasks without disruption. However, it might be a good idea for admins to inform their users about the changes ahead of time. A little heads-up can go a long way in ensuring a smooth transition!

As for the impact of these changes, it’s likely to be quite significant. Users will enjoy a more integrated experience, which could lead to enhanced productivity and satisfaction. Plus, with notifications from classic Outlook taking precedence during that session, users won’t miss important reminders—unless, of course, they’re too busy enjoying their cake!

I encourage everyone to share their thoughts on this update. How do you think it will affect your daily tasks? Will you be excited to use both versions of Outlook? Let’s get the conversation going!

This sounds helpful, especially for users in transition or in mixed environments where both versions of Outlook are in use. I wonder if this will pave the way for a smoother eventual migration.
