Error adding my Personal OneDrive account to the ODfB sync

Stefan Nordberg 

I’m sorry to hear that you’re having trouble adding your personal OneDrive account to your existing OneDrive for Business sync. Based on the error message you received, it seems that the email address you entered is not compatible with the service.

This issue could be due to a variety of factors. Here are a few potential solutions:

1.Switch Accounts: You could try switching to a local account from your Microsoft account, rebooting your computer, and then switching back to your desired Microsoft account.

2.Reset OneDrive: You could try resetting OneDrive. 

3.Check Group Policy: If you’re an administrator, you can check the Local Group Policy Editor to see if the option “Prevent Users from synchronizing personal OneDrive account” is enabled.

Please note that these are just potential solutions and might not solve the issue in all cases. Always make sure to back up your data before making any major changes to your system.
