How to Fix OneDrive Error 8004DED2 and 8004DED5

Product: Microsoft OneDrive and Outlook
Device & OS: not provided
Scenario: Attempting to sign into the OneDrive desktop application and using the Outlook Send to OneNote integration.
Observed behavior: OneDrive desktop sign-in fails with error 8004DED2 or 8004DED5 (high volume of requests) despite web access working properly. Outlook displays an error stating the tenant lacks a valid SharePoint license.

Before you start

Verify that your internet connection is stable and log into OneDrive via your web browser to confirm your account and credentials are active.

Solution 1Recommended

Test Alternative Networks and Local User Profiles

Determine if the sign-in error is caused by a local network restriction, a firewall, or a corrupted computer user profile.

If you can successfully view and edit your OneDrive files in a web browser, the issue is likely isolated to your local environment or desktop client. Testing different connection methods helps bypass local network blocks.

Switch to a mobile hotspot

Disconnect your computer from your current Wi-Fi or Ethernet network and connect it to your smartphone's mobile hotspot to bypass potential router or ISP restrictions.

Test on a new user profile

Create a temporary new local user profile on your operating system, log into that profile, and attempt to sign into OneDrive to see if your primary profile's cache is corrupted.

Check the mobile application

Download and open the OneDrive app on your iOS or Android device using the same network. If the mobile app also fails, the issue is likely related to the server or your tenant account.

Frequently Asked Questions

What does OneDrive error 8004DED5 mean?

Error code 8004DED5 typically indicates that the OneDrive authentication service is experiencing an unusually high volume of requests. This is usually a temporary server-side issue that resolves itself once traffic stabilizes.

Why does Outlook say my tenant lacks a valid SharePoint license?

This happens when your Microsoft 365 account synchronization fails, or your organization's IT administrator has not properly assigned a SharePoint license to your user account, which is required for the 'Send to OneNote' feature to function.

Will reinstalling the OneDrive desktop app fix error 8004DED2?

Reinstalling or resetting the OneDrive app can fix the error if it is caused by local file corruption. However, if the issue stems from organizational network restrictions or tenant licensing, reinstalling the app will not resolve the problem.
