Dear @Jasmine Bailey,
Thank you for reaching out to the Microsoft Q&A Community.
Based on your detailed description and the screenshots provided, it's clear you're facing a synchronization and authentication issue with your OneNote desktop app. The symptoms you describe including difficulties opening web notebooks on the desktop, failure to sync local notebooks, and permission errors all point to the same root cause: the OneNote desktop app cannot establish a proper, authenticated connection to your OneDrive account.
The error message "CONNECTED EXPERIENCES UNAVAILABLE" indicates that the app's link to the Microsoft cloud services, including OneDrive, is broken or restricted, which is why it can't access your notebooks or sync new ones. This also explains the "permission" error you received.
The most common cause for this type of issue is a corrupted or outdated set of cached credentials. Reinstalling the app doesn't always fix this because the credentials are saved elsewhere. You need to manually clear them.
- Close all Microsoft Office apps, including OneNote.
- Open the Windows Credential Manager. You can do this by typing "Credential Manager" into the Windows search bar.
- Click on Windows Credentials.
- Under the section labeled "Generic Credentials," look for any entries that mention "OneDrive Cached Credentials" or "MicrosoftOfficeXX_Data."
Expand each of these entries and click Remove.
Restart your computer, then open OneNote. It should prompt you to sign in again.
If clearing your credentials does not resolve the issue, it suggests the problem is not a simple cache error. It is highly likely that your organization's IT administrator has set a policy that is preventing the OneNote desktop app from accessing connected experiences. This is common in a business environment for security or compliance reasons.
Contact your IT admin; they have the access and tools to:
- Check your Microsoft 365 license and ensure it's configured correctly.
- Review any group policies or tenant settings that might be restricting your access.
- Investigate the issue further by opening a support ticket with Microsoft, if necessary.
I hope this information helps clarify the situation and provides you with workable solutions. Should you have any further questions or need additional assistance, please don't hesitate to reach out. We're always here to help. Have a wonderful day!
