How can I fix this problem when I want to connect my computer to my professional Onedrive

Hi @Raoul Laue,

Thank you for your response.

Since OneDrive works fine online but not on your computer, this points to a Windows client or OneDrive sync client issue on the device itself.

Because this requires deeper, device‑level troubleshooting, the best next step is to have Microsoft Support check the machine remotely.

Recommended next step:

Please open a support ticket in the Microsoft 365 admin center so that Microsoft Support can troubleshoot your device directly.

• If you are an admin: Go to https://admin.microsoft.com > Support > New service request
• If you do not have admin permissions: Please contact your IT administrator and ask them to submit the support ticket on your behalf. Microsoft Support can only provide remote assistance through an admin‑initiated request.

Please note that forum moderators do not have access to user account settings and cannot assist with logging in, resetting passwords, or changing access rights. While we do not have access to internal systems or administrative tools required to resolve account-specific or backend-related issues but we’ll continue doing our best to support you within the scope of our responsibilities.       

If you have any further questions or need assistance in the future, please don’t hesitate to reach out. I’ll be happy to help, and the moderators in the Microsoft Q&A forum are also here to support you.

Hi @Raoul Laue,

Thank you for the additional information.

Since your personal OneDrive (Gmail) syncs correctly and your professional OneDrive works normally on your laptop, the issue is very likely tied to authentication on this specific desktop.

Here are a few focused checks to help identify the root cause:

1/Verify that your professional account is actually a Microsoft 365–backed account

Some internet providers offer email addresses like name@isp.com, but not all of them are true Microsoft 365 work accounts.

Please try signing in from the affected computer:

• https://portal.office.com
• https://onedrive.live.com

If you can sign in normally: The account is valid, and the problem is local to Windows authentication on this device.

If you cannot sign in or see errors such as “account does not exist”:

Your provider may not be using Microsoft 365 or the account may be configured differently.

2/ Check whether your ISP uses “alias authentication” or a non‑standard Microsoft login

Some providers authenticate email accounts through their own identity system instead of Microsoft’s. This can lead to:

• token refresh failures on certain devices
• authentication loops on Windows
• OneDrive sign‑in working on one computer but not another

If possible, please ask your provider whether your professional email is:

• a true Microsoft 365 business/work account, or
• a standard POP/IMAP account with a linked legacy Microsoft account used to access OneDrive

This distinction is important because Windows sign‑in tokens behave differently depending on the account type.

If the issue continues:

At this stage, since the error persists even after reinstalling OneDrive and clearing cached credentials, the next step is to involve your internet provider. They can:

• verify how your account is configured
• reset the authentication profile if needed
• open a support ticket with Microsoft if it’s a tenant-level issue.

I hope this information is helpful. Should you have any further questions or need additional assistance, feel free to reach out.

Hi Kristen

Thanks for the feedback but it did not solve the problem.

I realy need to figure out how to solve this problem.

On my computer I usually have 2 OneDrive: a Professional and a private one.
The private one is linked to my Gmail and I have no problem to install that one on my computer

The professional is linked to my profesionnal email which is provided by my internet supplier.

I did uninstall both of them and reinstall them. I still got the same error message with my profesionnal e-mail. Is it something that can be related to my internet provider?

The strange think is that on my laptop I have the same set up (2 oneDrive) and on that one I do not have any problem

Thanks for the help.

Hi @Raoul Laue,

Welcome to Microsoft Q&A forum.  

Thank you for reaching out. I understand you're currently unable to sync OneDrive on your device and are seeing the error “The credential is invalid. Unexpected sub status (6008)”. This typically indicates that your Windows profile is attempting to authenticate using outdated or corrupted sign‑in tokens.

To narrow down the cause, could you first try signing in at https://office.com and accessing OneDrive on the web?

• If you can sign in, your account is working correctly, and the issue is isolated to the local credentials on your device.
• If you cannot sign in, the issue may be account‑ or policy‑related, and your IT department may need to review it.

Here are suggestion steps you can try to troubleshoot:

1/ Sign out and completely close OneDrive

• Right‑click the OneDrive cloud icon in the taskbar and choose Quit OneDrive.
• If the icon isn’t visible, open Task Manager and End task for OneDrive.exe.

2/ Clear cached authentication data (WAM/AAD + Credential Manager)

a. Delete Azure AD Broker Plugin cache

Open File Explorer and paste the following path:

%localappdata%\Packages\Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy

Delete all files and folders inside.

b. Remove stored Windows credentials:

Go to Control Panel > Credential Manager > Windows Credentials and remove entries related to:

• MicrosoftOffice / Office
• OneDrive
• ADAL
• msteams
• Any entries containing your work email or tenant Then restart your device.

c. (Optional but helpful) Clear additional token caches:

Delete the contents of the following folders:

%localappdata%\Microsoft\OneAuth
%localappdata%\Microsoft\IdentityCache

This often resolves stubborn sign‑in loops.

d. Remove OneDrive’s pre‑sign‑in settings file:

%localappdata%\Microsoft\OneDrive\settings\PreSignInSettingsConfig.json

Delete this file if it exists.

Reference: Clear OneDrive cached credentials.

3/ Re‑register your device under “Access work or school”

Go to Settings > Accounts > Access work or school:

• Select your work account > Disconnect
• Restart your device
• Return to the same menu and Connect your account again

This refreshes your device registration and creates new authentication tokens.

(If the Disconnect option is disabled due to your organization’s policies, you may need IT assistance.)

4/ Reset the OneDrive client

Run this command (Win + R):

%localappdata%\Microsoft\OneDrive\onedrive.exe /reset

Wait a moment. If OneDrive doesn’t restart automatically, launch it from the Start menu and sign in again.

5/ If the issue continues

If the problem persists, I recommend contacting your IT administrator for further investigation. They can review the sign‑in logs associated with the Correlation ID or open a support ticket to Microsoft support through Microsoft 365 Admin Center if needed.

I hope this information helps. Please try the steps and let me know whether they resolve the issue. If the problem persists, we can work together to find a solution.
