Symptom
- User can open onenote application.
- When clicked to sync, error message is displayed as below:
OneNote cannot connect to the server. If a problem occurs please verify Firewall,VPN, Proxy settings. Error code: 0x10000”
- Traffic decryption is enabled on the firewall
- certificate-related errors are seen on the onenote application.
certificate error 0x10000 - cert_trust_is_partial_chainEnvironment
- Palo Alto Firewalls
- Supported PAN-OS
- Onenote application
- Decryption enabled
Cause
- Onedrive IP address range is 13.107.136.0/22.
- The one drive content sync address URL is "contentsync.onenote.com".
- If this oneNote IP address or contentsync.onenote.com is decrypted, this causes the sync to fail.
Resolution
- Add the URL "contentsync.onenote.com" to the decryption exclusion list.
- Bypass decryption for the onedrive IP range.
- Alternatively, create a no-decrypt policy or bypass decryption for the user.
