Contact Your Microsoft 365 Administrator for Support
Because this synchronization failure typically occurs in a Microsoft 365 Business environment, it requires backend troubleshooting by a system administrator.
In enterprise or business environments, calendar syncing between Outlook and OneNote is managed by Microsoft 365 servers. When local troubleshooting fails, the issue is often tied to tenant-level server disruptions or account configuration errors.
Make a list of the exact meetings that are missing or outdated, including dates, times, and the affected email accounts.
Open OneNote and Outlook, navigate to File > Account, and note down the exact version and build numbers of both applications.
Contact your company's Microsoft 365 Administrator and ask them to open an official support ticket through the Microsoft 365 Admin Center using the details you gathered.

Frequently Asked Questions
Why are recent calendar updates not reflecting in OneNote?
This usually happens due to a synchronization delay between Outlook and OneNote servers. If the servers fail to communicate recent changes, the Meeting Details will remain outdated until the connection is restored.
Can I manually force OneNote to sync my meeting details?
Yes, you can try forcing a sync by right-clicking your notebook's name and selecting 'Sync This Notebook Now', or by pressing Shift+F9 on your keyboard.
Does signing out and back in fix the meeting details issue?
Signing out of your Microsoft 365 account in OneNote and signing back in can sometimes refresh your credentials and force a new sync, but it will not fix underlying server-side issues requiring administrator intervention.
