Trying to Sign in to My Device with Microsoft Account routes to Personal Account after adding account and associating user

Good day @Fadi Abadir,  

Thank you for sharing your concern.  

To sign in with a work account as a separate profile, you need Windows 10/11 (or Pro) or Enterprise, since Home edition only lets you add a work account for apps but not use it as the main login or manage the device. 

• First, check which Windows edition your device is running, as signing in with a work account depends on it. Please go to Settings > System > About. 

Please refer to the scenario that best matches your situation: 

Scenario 1: If your device is Windows 11 Pro, Enterprise, or Education 

Your device fully supports signing in with a work account and joining Microsoft Entra ID. Please follow these steps carefully to ensure correct setup: 

• Step 1: Properly join the device to work account 

Open Settings > Go to Accounts > Select Access work or school > Click Connect. 

Choose Join this device to Azure Active Directory. 

Sign in using your work account. 

After completing, confirm the device shows as connected to Microsoft Entra ID. 

• Step 2: Sign in using the work account 

Click Start menu > Select your user profile icon > Choose Switch user. 

Sign in using your work account credentials. 

This will create a separate work profile tied to your organization. 

• If the system still redirects to a personal account, this usually happens because the same email is registered as both a personal Microsoft account and a work account. 

To avoid this conflict: 

Make sure no personal Microsoft account is signed in on the device. 

Go to Settings > Accounts > Emails & accounts and remove any personal accounts. 

Open Credential Manager and remove saved Microsoft credentials in both Web and Windows Credentials. 

Restart the device and repeat the join steps above. 

Scenario 2: If your device is Windows 10/11 Home 

Windows Home does not support signing in with a work account at the device level. This is why you are being redirected to a personal account. 

• Option 1: Upgrade to Windows 10/11 (Pro) 

This is the recommended approach for your business use case. 

Open Settings > Go to System > Activation. 

Select Upgrade your edition of Windows. 

Follow the prompts to upgrade to Pro. 

After upgrading, you can follow the steps in Scenario 1 to join the device properly. 

Note: You may consider backing up important data before upgrading to avoid unexpected data loss. Please visit this article to know more how to back up your data in Windows: Back up and restore with Windows Backup - Microsoft Support  

• Option 2: Continue using Windows Home  

If upgrading is not possible: 

Sign in to Windows using a local account or personal Microsoft account. 

Go to Settings > Accounts > Access work or school. 

Add your work account. 

This allows access to apps like Outlook, Teams, and Office, but does not allow: 

• Signing into Windows with the work account. 
• Device management or domain-style control.
