Revert to Legacy Outlook for Mac

The new Outlook for Mac does not currently fully support the Notes functionality. Reverting to the legacy version is the most reliable way to access and restore them.

Microsoft's updated Outlook interface for macOS omits several legacy features, including the traditional Notes module. Toggling back to the older version forces the application to reload your original profile structure, which should reveal the hidden Notes.

1
Open the Help Menu

Launch Microsoft Outlook on your Mac. Click on the 'Help' menu located in the top menu bar.

2
Revert to Legacy Outlook

Select the option that says 'Revert to Legacy Outlook' from the dropdown list.

3
Confirm the Switch

Confirm your choice when prompted. Outlook will restart in the classic interface, and your Notes should now be visible in the navigation pane.

Export Recommendation: Once you successfully access your Notes in the legacy version, it is highly recommended to export them to an .olm file for safekeeping.

Frequently Asked Questions

Why did my Notes disappear when I updated Outlook for Mac?

Microsoft's 'New Outlook for Mac' currently lacks native support for the traditional Notes feature. Upgrading or switching interfaces hides them simply because the new application architecture does not display that specific data type.

Can I recover Outlook Notes that aren't in the Deleted Items folder?

Yes. If your account is synced with an Exchange server, check Outlook on the Web first. If they are missing there, your Microsoft 365 administrator may be able to restore them using Exchange Admin Center retention policies.

Are Mac's built-in Apple Notes connected to Outlook Notes?

If properly configured, Microsoft Exchange accounts can sync note data to the default Apple Notes app. You can check the Apple Notes app under the 'Exchange' account tab to see if your items appear there.
