If you're encountering the error "We couldn't find a work or school account with that email address" while trying to set up your Microsoft 365 subscription in the New Outlook, it may be due to a few reasons:
- Incorrect Email Address: Ensure that the email address you are entering is correct and associated with your Microsoft 365 subscription.
- Account Type: Make sure that the account you are trying to add is indeed a work or school account. Personal accounts may not be recognized in this context.
- Autodiscover Issues: If you have migrated your mailbox or made changes to your account settings, there might be issues with Autodiscover that prevent the New Outlook from properly configuring your account.
- Updates: Ensure that you are using the latest version of the New Outlook, as older versions may have bugs or compatibility issues that have since been resolved.
If the problem persists, you may want to try the following steps:
- Verify your account details on the Microsoft 365 portal.
- Check for any service outages that might be affecting account setup.
- Consider running the Classic Outlook Profile Setup troubleshooter to help configure your account correctly.
If none of these solutions work, you may need to contact Microsoft support for further assistance.
