Hi Mattias,
Your time is appreciated. If you have a online repair, you don't need to set up your account again. May I know if you have created a new profile? If so, you can try to switch to another profile. For your reference:
Since you mentioned that you couldn't set up your work account, if it is an Office 365 for Business account, please try Support and Recovery Assistant for Office 365 tool. For your reference:
If the issue persists, could you please share more details about it?
- Did you get any error message? If so, could you please provide a screenshot of it?
- Can you send/ receive emails using your work account?
- Please let me know whether the only issue is that you cannot find your previous emails in your work account.
- Can you find your previous emails in OWA(Outlook Web App)?
Regards,
Carlos
