OneDrive error code 0x8004de26
We are a school system and are having an issue with our OneDrive app not allowing us to sign in. Things had been working until about 2 weeks ago and things stopped. We are having the issue across multiple users. We are on Windows 11 laptops and desktops and are trying to sign into the app to get items saved in on the desktop to syn with OneDrive accounts in the cloud. The sign-in process either simply spins or we get error code0x8004de26. I am wondering if anyone has resolved the same issue or has ideas? Thank you.

OneDrive Error 0x8004de26
This error typically means:
OneDrive cannot authenticate because the account type or sign-in method is blocked, mismatched, or disabled by your organization.
This indicates that the issue is affecting multiple users, not just a few.
This aligns with causes such as:
- Security Defaults or Conditional Access changes
- License or permission changes in Microsoft 365
- Firewall or network filtering affecting all devices
It’s not an isolated user/device issue, so troubleshooting should focus on tenant settings, policies, and OneDrive client configuration across the environment.
As an admin in a school or EDU Microsoft 365 tenant, here’s a step-by-step action plan to resolve OneDrive error 0x8004de26 across multiple users:
Check User Licenses
(Missing licenses will prevent OneDrive from signing in.)
Review Security Defaults & Conditional Access Policies
(Temporarily disable policies or security defaults for testing to see if users can sign in.)
Check SharePoint & OneDrive Sync Settings
(Make sure “Users can sync files from SharePoint using the OneDrive client” is enabled)
Hope this helps you a little bit.
