In a service alert spotted by BleepingComputer, Microsoft revealed that the glitch started on February 5 and has been preventing some Exchange Online users from sending and receiving emails. "Some users' legitimate email messages are being marked as phish and quarantined in Exchange Online," Microsoft said in the service alert. "We've determined that the URLs associated with these email messages are incorrectly marked as phish and quarantined in Exchange Online due to ever-evolving criteria aimed at identifying suspicious email messages, as spam and phishing techniques have become more sophisticated in avoiding detection."

GitHub engineers recently traced user reports of unexpected "Too Many Requests" errors to abuse-mitigation rules that had accidentally remained active long after the incidents that prompted them. According to GitHub, the affected users were not generating high-volume traffic; they were "making a handful of normal requests" that still tripped protections. The investigation found that older incident rules were based on traffic patterns that were strongly associated with abuse at the time, but later began matching some legitimate, logged-out requests.

To work around those rules, the Humanizer skill tells Claude to replace inflated language with plain facts and offers this example transformation: Before: "The Statistical Institute of Catalonia was officially established in 1989, marking a pivotal moment in the evolution of regional statistics in Spain." After: "The Statistical Institute of Catalonia was established in 1989 to collect and publish regional statistics." Claude will read that and do its best as a pattern-matching machine to create an output that matches the context of the conversation or task at hand.
