    TheRegister is reporting that this afternoon, a glitch in Microsoft Office 365's spam filters caused all incoming emails to be tossed into the junk folder. By around 5pm Pacific time, Microsoft said it had fixed the issue. "We've addressed the underlying issue and affected emails are being refiled into the right folder,” a spokesperson told The Register.

    First Gmail users spamming themselves, and now Microsoft doing the ultimate in spam filtering by blocking everything, it's been a rough week for email. Thanks to cageymaru for the story.

    This issue must have been localized/sporadic. I run O365 with Exchange and didn't have this issue at all today.

    Yes, it had to be localized. Because of where our corporate HQ is, our systems are in the midwest data centers, but most of our clients are located in the US East data centers, and none of them (many dozens of companies we've migrated to O365) reported any issues.

    Status: Service degradation

    User impact: Users may experience legitimate email being marked as a phishing scam.

    Latest message: Title: Email is being marked incorrectly as a phishing scam

    User Impact: Users may experience legitimate email being marked as a phishing scam.

    More info: Affected messages will contain "Proofpoint.com" in the message, body or HTML markup. A banner will be displayed that says "This message was identified as a phishing scam."

    Current status: We're performing a final validation for the solution, which will move the affected messages back to their appropriate folders, and we'll begin deployment once the validation is complete. The messages will still have the phishing scam banner displayed, even after they are moved to the appropriate folders.

    Scope of impact: This issue could potentially affect any of your users intermittently if they have received an email containing "Proofpoint.com" in the message, body or HTML markup.

    Start time: Wednesday, April 25, 2018, at 7:30 PM UTC Preliminary root cause: A recent change to phishing detection settings, implemented by monitoring and response systems, caused certain messages to be incorrectly identified as phishing scams. Next update by: Thursday, April 26, 2018, at 3:00 AM UTC

    Well, they aren't wrong on about 90% of e-mails.

    This just in: Microsoft Security Essentials just flagged Windows as malware, and deleted all installations of Windows worldwide.

    The world breathes a sigh of relief.
