Microsoft’s Exchange Online Comedy of Errors: When Anti-Spam Goes Rogue
Microsoft is currently investigating an Exchange Online bug where anti-spam systems are going on an email-quarantining spree. Some emails are being mistakenly flagged and quarantined, leaving users wondering if their messages are secretly moonlighting as spam. Meanwhile, Microsoft’s engineers are working to correct the issue, but it seems emails are in no hurry to leave quarantine.
Hot Take:
Looks like Microsoft’s Exchange Online is trying its hand at a new role: the overzealous bouncer at the cyber-club, sending perfectly nice emails to the quarantine corner. Maybe it’s time for Microsoft to hire a new gatekeeper or at least get this one some glasses!
Key Points:
- Microsoft is investigating a bug in Exchange Online’s anti-spam system causing email quarantines.
- The issue started at 10:11 UTC and is considered a critical service issue.
- Efforts to whitelist affected URLs have not been successful so far.
- A separate incident is causing the ‘Review’ page in the Security portal to be inaccessible.
- Microsoft previously resolved similar issues with Exchange Online false positives.
