Revert to Classic Outlook or Send Directly from Outlook

The 'New Outlook' web-based experience often breaks direct integration with the OneNote desktop app. Reverting to classic Outlook or pushing notes from Outlook usually bypasses this limitation.

Microsoft's transition to the 'New Outlook' essentially replaces the traditional desktop client with a web wrapper. This change disrupts the local COM integration that the OneNote desktop application relies on to read your calendar.

1
Toggle off New Outlook

In the top right corner of the New Outlook window, locate the 'New Outlook' toggle switch. Turn it off to revert to the classic desktop version of Outlook.

2
Restart both applications

Close both Outlook and OneNote completely. Reopen them to allow the classic COM add-ins and background integration processes to refresh.

3
Use the Send to OneNote feature

If you prefer or are required to keep using New Outlook, open the meeting directly in Outlook, click the 'Send to OneNote' button in the ribbon, and choose your destination notebook.

Frequently Asked Questions

Why did OneNote suddenly stop syncing with my Outlook calendar?

This issue is most frequently caused by a recent Office software update, automatically switching to the 'New Outlook' version, or temporary authentication mismatches between your Microsoft account sessions in both apps.

Can I still link meetings to OneNote while using the New Outlook?

Yes, but direct retrieval originating from within OneNote may fail. You must push the meeting details instead by opening the event inside Outlook and selecting the 'Send to OneNote' option from the ribbon.

Will repairing Microsoft 365 delete my notebooks or emails?

No, running a Quick Repair or Online Repair from Windows Settings will only restore the application files, registry keys, and software configurations. Your personal notebooks, emails, and locally stored data will remain completely intact.
