Summary

Starting mid-September to late October 2025, new Outlook for Windows will allow sharing local Word, Excel, and PowerPoint files via right-click Share in File Explorer. This replaces the old Outlook sharing method and requires no admin action, though user notification is recommended.

More information

Updated July 28, 2025: We have updated the timeline. Thank you for your patience.

Coming soon to new Microsoft Outlook: Users will be able to share Microsoft Word, Microsoft Excel and Microsoft PowerPoint files stored on their device (not stored in a cloud like Microsoft OneDrive) from new Outlook for Windows.

This message is associated with Microsoft 365 Roadmap ID 397094.

When this will happen:

General Availability (Worldwide, GCC): We will begin rolling out mid-September 2025 (previously early July 2025) and expect to complete by late October 2025 (previously late August). 

How this will affect your organization:

Before this rollout, users are only able to see old Outlook for Windows when they try to share a Word, Excel or PowerPoint fie.

After this rollout, when users want to share a Word, Excel, or PowerPoint file that is saved to their device (not stored in a cloud like Microsoft OneDrive), the user can right-click the file name in File Explorer, select Share, and select new Outlook for Windows to email the file.

This option is on by default.

What you need to do to prepare:

This rollout will happen automatically by the specified date with no admin action required before the rollout. You may want to notify your users about this change and update any relevant documentation.
