Hi Brad Madden,
Thank you for posting your query on Microsoft Q&A. I am Saiteja from Q&A will be assisting you with your query. Based on the information provided, here is my understanding: When a user tries to sign in it states, "Something went wrong" and asks for sign in which creates an entry which is leading for multiple duplicate accounts. As per the error, I see this issue comes whenever there is no proper registration has not happened with the device or if there are any policies which might not be satisfying from Intune.
I would like to segregate the issue before going for any solution. Could you please check the user work or school account status and check if it is properly configured as your requirement (Azure AD join or Azure AD registered).
If there is any error stating sign in, kindly re register the device. If you would like to go with Azure Ad register or join, kindly following this document. Here you need to choose to add existing device to Azure.
- Open Settings, and then select Accounts.
- Select Access work or school, and then select Connect.
- Here on "Set up work or school account" if you provide credentials, this is going to be an Azure AD register device.
- If you would like to set up the device as Azure AD join, you need to choose "Join the device to Azure Active directory".
- Once you are finished, restart the device and check the scenario.
If this does not help you or if you are not working with device registration with Azure and the device has issues with Intune itself, here is the document that helps you in solving the issue from Intune. The document I shared is to check the required troubleshooting steps from Intune for the same error which covers the Intune policies and certificate to be checked to resolve the issue.
I hope this information is helpful. Please feel free to reach out if you have any further questions.
