If the new account in your Office 365 setup is not seeing shared OneDrive folders, there are a few potential reasons and steps you can take to troubleshoot the issue:
- Permissions Check: Ensure that the shared folders have been properly shared with the new account. The sharing permissions must be correctly set for the new user to access the folders.
- Account Configuration: Sometimes, there may be a mismatch in the account configuration. Verify that the new account is set up correctly in the Microsoft 365 admin center and that it has the necessary licenses to access OneDrive.
- Linking Issues: Since you mentioned unlinking and relinking the account, ensure that the relinking process is completed successfully. Sometimes, it may require a complete sign-out from OneDrive and then signing back in.
- User Principal Name (UPN) Mismatch: If the new account was created using a UPN that was previously used by another account, there could be a site user ID mismatch. This can prevent access to shared folders. You may need to check for any UPN conflicts and resolve them.
- Access Denied Errors: If the account is still facing issues, it might be beneficial to check if there are any access denied errors or permission issues that could be affecting the new account's ability to see shared content.
If the problem persists after checking these points, consider reaching out to Microsoft support for further assistance.
