I Understand how frustrating it can be when you’re trying to sign in to an old Hotmail account, but you’re getting conflicting messages saying the address doesn’t exist while also being told it’s already in use, which is very frustrating.
To help resolve this as quickly as possible, could you please confirm the following details:
- Approximately when was the last time you successfully signed in to this Hotmail account?
- Have you already tried the Microsoft account recovery form at least once for this email address?
I look forward to your reply so we can continue working together to address the issue.
