Hi, I'm John! I will help you with this.
To help narrow down the issue:
- Are you trying to sign in on a phone, tablet, or computer? What exact error message do you see when signing in?
- Is the old account still active, or have you not used it for a long time?
- Is the account an Outlook.com email address, or a different email provider? Are your photos still visible at https://onedrive.live.com when signing in from a browser?
