Fix OneDrive for Mac Sign-In Error Code 8004de86
Question details
The user needs to resolve OneDrive for Mac sign-in error 8004de86, which occurs despite other Office apps working and basic troubleshooting steps failing.
- Product
- OneDrive for Mac
- Device & OS
- macOS
- Scenario
- Signing in to the OneDrive desktop application on a Mac.
- Observed behavior
- Error code 8004de86 appears during the sign-in process, indicating a profile-specific configuration problem that standard app resets and reinstallations do not fix.
Ensure you have your Microsoft account credentials ready and verify that you have administrative privileges on your Mac to create a new user environment.
Create and Test with a New macOS User Profile
Use this solution to isolate and bypass corrupted local user profile settings that are causing the sign-in error.
Since standard troubleshooting steps such as reinstalling the app, resetting OneDrive, or clearing Keychain entries often fail to fix error 8004de86, the issue is typically tied to your specific macOS user profile. Creating a fresh macOS user profile allows OneDrive to authenticate without interference from corrupted local background data.
Click the Apple menu in the top-left corner of your screen and select System Settings (or System Preferences on older versions of macOS).
Navigate to Users & Groups, click the Add Account button, and authenticate with your current administrator password to unlock the settings.
Set the new account type to Administrator, fill in the required account details such as full name and password, and click Create User.
Log out of your current macOS session, log in with the newly created profile, launch OneDrive from the Applications folder, and attempt to sign in.

Frequently Asked Questions
Why does OneDrive error 8004de86 occur only on one Mac user profile?
This error is typically caused by corrupted local cache files, broken keychain tokens, or conflicting background processes that are specific to your individual user environment. Testing on a new profile bypasses these corrupted local elements.
Can I fix the error without creating a new macOS user profile?
You can attempt to completely remove all OneDrive cached data from the hidden ~/Library/ folders and delete all Microsoft-related Keychain Access entries. However, creating a new profile is the most definitive way to test if the issue is truly profile-specific.
Where can I find my exact OneDrive version on a Mac?
Click the OneDrive cloud icon in your Mac menu bar, select the Help & Settings gear icon, click Preferences, and navigate to the About tab to view your current application version number.
Will reinstalling Microsoft Office and OneDrive fix error 8004de86?
Typically, simply reinstalling the application does not fix this specific error because the problematic configuration files, caches, and credentials remain intact within your macOS user profile even after the app is uninstalled.
