Can't log into OneDrive, getting error 0x8004deef or browses to users OneDrive online

Question

We found an issue where the OneDrive client would not sign in and the OneDrive portal would not load for a new user, after recreating the profile and removing / re-adding license we then found the UPN to differ to the primary email account due to a local Azure AD sync problem this then led us onto find most of this fix as below that has been mentioned before but by default you should apply everyone except external users via the below steps this should then provide the fix for the source of the problem longer term. Also added the powershell to force the creation of the SharePoint site

1. Log into your SharePoint admin account
2. Open the admin center
3. Hit "Show All" in the left pane and go to SharePoint admin center
4. In the Classic SharePoint admin center, go to "user profiles" in the left pane
5. Under "People" click "Manage User Permissions"
6. For each user having issues, type their name into the box and hit "Add"
7. Add everyone except from external users, and then assign them all permissions (Create, Follow, Use)
8. Hit OK
9. Then you can force it to re create it by remove / re-adding license after 15 mins or use these power shell commands
10. Install-Module -Name Microsoft.Online.SharePoint.PowerShell Connect-SPOService -Url https://yoursharepoint-admin.sharepoint.com/ Request-SPOPersonalSite -UserEmails ******@domainname.com

Worth mentioning that removing everyone can also stop users having OneDrive folders if that is a preference as well

To resolve the issue of not being able to log into OneDrive and encountering the error code 0x8004deef, you can follow these steps:

1. Check License Assignment: Ensure that the user has a valid OneDrive license assigned. This can be done by a Microsoft 365 administrator in the admin center. Navigate to Users > Active users, select the user, and check under Licenses and apps to confirm that a OneDrive license is assigned.
2. Remove Cached Account Identities: If the license is valid, you may need to clear cached account identities. This involves modifying the registry:
   • Open the Registry Editor.
   • Navigate to HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Common\Identity.
   • Right-click on Identity and select Delete. If Shared Computer Activation is enabled, also delete the corresponding subkey for the user SID.
3. Use Microsoft Support and Recovery Assistant: If the issue persists, you can download and run the Microsoft 365 Support and Recovery Assistant to help diagnose and fix the problem.
4. Check for UPN Issues: Since you mentioned a potential UPN mismatch due to Azure AD sync issues, ensure that the UPN matches the primary email account. This can be critical for proper sign-in functionality.
5. Force Creation of SharePoint Site: If necessary, you can use PowerShell commands to force the creation of the SharePoint site for the user. This involves connecting to the SharePoint service and requesting a personal site for the user.

By following these steps, you should be able to resolve the sign-in issue with OneDrive and ensure that the user has the necessary permissions and configurations set up correctly.
