You may have noticed an increase in emails that look like they come from your own company or other familiar senders. This is a known, industry‑wide issue affecting Microsoft 365 and other email platforms, caused by criminals getting better at impersonating trusted email addresses—not because your account or Microsoft’s systems have been hacked.
These messages are designed to blend in with normal work emails (such as voicemails, shared documents, or password notices) to trick recipients into clicking links or opening attachments. Microsoft is actively blocking millions of these emails, but no system can stop every attempt.
The most important thing to remember is to be cautious with unexpected messages, especially those that ask you to act quickly, click a link, or enter login information. When in doubt, pause and verify before taking action.
