New Microsoft Outlook for web and Windows: Organize and reorder folders

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

Coming soon: We will automatically import the folder order from classic Microsoft Outlook for Windows to new Microsoft Outlook for Windows and Outlook for the web. If users have not customized their folder order, the default view will continue to display folders alphabetically in the new Outlook.

This message is associated with Microsoft 365 Roadmap ID 378775.

When this will happen

Targeted Release: We will begin rolling out late November 2024 (previously early October) and expect to complete by late December 2024 (previously early November).

General Availability (Worldwide): We will begin rolling out January 2025 (previously early November) and expect to complete by early February 2025 (previously early December).

General Availability (GCC, GCC High, DoD): We will begin rolling out early February 2025 (previously early December) and expect to complete by early May 2025 (previously early March).

How this will affect your organization

Before this rollout: If a user enabled custom folder order in classic Outlook, the custom order is preserved in the new Outlook for Windows and Outlook on the web. This may result in changes to the folder structure for affected users, as the new Outlook supports only alphabetical ordering.

After this rollout: users will see the custom folder order they previously enabled in classic Outlook. Special folders such as Inbox, Drafts, Sent Items, and others will still remain at the top of the folder list, even when the rest of the folders are arranged alphabetically.

This change is on by default.

To change folder order, go to the new Outlook ribbon, and select View > Layout > Folder pane. Choose one of these options:

• Order folders A to Z order: This will organize folders alphabetically
• Custom order

Users can hover next to each folder name to see the three-dot menu where they can move folders with drag-and-drop or the move up/move down options:

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.
