Microsoft has officially ramped up Outlook’s security, blocking two additional executable file types. While specific extensions remain unconfirmed, these changes target high-risk attachments capable of running malicious code. Expect Outlook to reject these files instantly. To maintain productivity, ditch direct attachments and switch to secure cloud-storage links. Keep your workflows safe, compliant, and ready for this new era of email protection.
