What if I keep getting spam from different email addresses?
If you notice multiple spam senders, create a separate rule for each one. It’s better to make rules as specific as possible so you only block unwanted emails. Broad or general rules may accidentally catch legitimate messages and prevent them from reaching your inbox.
What if a legitimate email ends up in my Junk folder?
Check your Junk folder regularly. If you find a legitimate message there, right-click it and choose Mark as Not Junk. This helps Outlook learn and prevents similar emails from being flagged in the future.
Can I edit or remove a rule after I create it?
Yes. In Outlook, you can go to Manage Rules & Alerts to review, edit, or delete any rule you’ve set up. This is useful if your needs change or you want to refine how messages are handled.
How often should I review my rules?
It’s a good idea to review your rules every few months. This ensures they’re still relevant and not blocking messages you actually want to receive.
What’s the difference between deleting an email and marking it as Junk?
Deleting an email simply removes it from your inbox. Marking an email as Junk not only moves it to your Junk folder but also notifies Microsoft, which helps improve filtering and protect all Outlook users from spam and phishing.
What if I block someone but still get emails from them?
Spammers often use multiple or changing email addresses. If you keep getting unwanted messages, it’s likely they’re coming from a different address. Just continue blocking or creating new rules for each new address you receive messages from.
