Using classic Outlook for Windows in business environments
It sounds like you're experiencing a common issue with spam emails. Despite blocking the sender, the emails keep coming, suggesting the sender is using multiple addresses or techniques to bypass filters. This pattern, especially with promises of winnings or urgent actions, is typical of phishing attempts. It's crucial not to open or interact with these emails, as they might contain harmful links or attachments. Instead, mark them as spam, and consider tightening your email security settings. Additionally, you may want to review your account's security and consider changing your password to ensure your email hasn't been compromised.
