Frequently Asked Questions

Why am I suddenly receiving thousands of missed-call emails?

This is typically the result of a coordinated phishing or spam campaign targeting your email address. Attackers use automated tools to flood inboxes, hoping the recipient will panic and click a malicious link to check the 'missed call'.

Can receiving spam emails infect my computer with a virus?

Simply receiving or viewing the plain text of an email usually cannot infect your computer. However, clicking on links, downloading attached files, or enabling active content within the email can expose your device to malware.

How can I stop these unknown senders from emailing me in Outlook?

You can use the 'Block Sender' feature or set up specific Inbox Rules in Outlook. By creating a rule that automatically routes emails containing specific phrases like 'Urgent: Missed-Call' directly to your Deleted Items folder, you can keep your inbox clean.

Should I reply to the sender to tell them to stop?

No, you should never reply to spam or phishing emails. Replying only confirms to the attacker that your email address is active and monitored, which will likely result in even more spam being sent to your inbox.
