OneNote keeps lagging and not responding after convert into OneNote 365

I am writing to report a persistent issue I’ve been experiencing with OneNote since migrating to OneNote 365. The application frequently lags, becomes unresponsive, and occasionally crashes during routine use. This has significantly impacted my productivity, especially when working with larger notebooks or switching between sections.

Prior to the upgrade, OneNote was functioning smoothly. The current performance issues seem to have surfaced only after the transition to OneNote 365. I have already attempted basic troubleshooting steps such as restarting the application, clearing cache, and updating to the latest version and Windows Recovery, but the problem persists.

Could you please advise on any known fixes or further steps I can take to resolve this? If needed, I’m happy to provide system details or logs to assist with diagnosis.

Looking forward to your guidance.

Warm regards,

Dr. Manoj Patel

    I’m reaching out regarding persistent lagging and unresponsiveness in OneNote. I’ve answered the questions below to help you better understand the issue:

    1. Activity Causing Lag: Whenever I switch between pens or scroll through a page, OneNote frequently becomes unresponsive. This issue did not occur when I used OneNote for Windows 10. I’m currently using a Microsoft Surface Pro 7 and have an active OneDrive subscription.
    2. Other Users Affected: Yes, all faculty members at my college are experiencing the same issue.
    3. Tried on Other Devices: I’ve tested the same OneNote files on different devices, but the problem persists. But OneNote for Windows 10 is working well on the same devices.
    4. Specific Files or Sections: The lag appears across all notebooks and sections, not just large files.
    5. Web Version: I’ve also tried using OneNote on the web, but the issue remains.
    6. Add-ins or Plugins: I do not use any add-ins or plugins with OneNote.
    7. Battery Settings: I’ve already set the battery performance to maximum, but it hasn’t resolved the issue.
