Microsoft anti-spam bug blocks URLs in Exchange, Teams

🔒 Microsoft is addressing a known anti-spam issue that has caused its service to incorrectly block URLs in Exchange Online and Microsoft Teams, and to quarantine some messages. The engine erroneously flags URLs embedded inside other URLs as malicious, creating alerts and preventing users from opening links that were already confirmed safe. Engineers deployed a fix to stop further quarantines and are unblocking over 6,000 affected URLs, but additional impacted links and residual message recovery remain under active remediation while a root cause analysis continues.
