A widespread Microsoft outage on Thursday left thousands of users struggling to access their emails, disrupting workplaces and government operations around the world.
The outage affected Outlook, Teams, Copilot, and other Microsoft 365 services. In updates on X, Microsoft said overloaded infrastructure and unresponsive servers were contributing to the disruptions, which continued into Friday.
“We regret that today’s outages caused disruptions for our customers, and we are working to address the issue,” Microsoft executive Charles Lamanna said in a Thursday post on X. “We will continue to share more information as soon as we have it, and for now I can confirm that there is no indication this is the result of malicious or cyber activity.”
The company did not immediately respond to a request for comment from Business Insider.
Some employees around the world are celebrating the outage, saying they can’t possibly work without their Teams and emails, and are jokingly suggesting their bosses give them Friday off. Others, in angry social media posts, are calling on Microsoft to resolve the issue soon so they can get back to work.
But for some of the world’s most successful business leaders, going without email is already a way of life.
Several CEOs and entrepreneurs have previously told Business Insider that they rarely use email, preferring phone calls, text messages, or even handwritten letters.
Kevin O’Leary
“Shark Tank” investor Kevin O’Leary said in a December interview with Business Insider that he had given up on email after being inundated with thousands of messages daily.
“I don’t do emails anymore because I get anywhere from 2,000 to 4,000 a day,” he said.
O’Leary said he had tried different filtering systems but couldn’t escape the constant stream of messages. People who need to reach him now use messaging apps instead, he added.

The Airbnb CEO is another email skeptic.
“I don’t know if I write an email a week,” Chesky told Time in a September interview.
He said he responds to emails daily but rarely initiates them, preferring texts, calls, and in-person conversations.
“I just find it inferior to almost every other form of communication,” Chesky said, explaining that texts feel more personal and faster.
John Paul DeJoria
DeJoria, the billionaire cofounder of haircare brands John Paul Mitchell Systems and Patrón Tequila, takes things further.
“I don’t even own a computer,” DeJoria told Business Insider in a June interview.
The 82-year-old entrepreneur said he doesn’t have an email address. Instead, he uses his assistant’s computer when necessary and prefers calls or handwritten letters.

The celebrity chef also favors phone calls over email when managing his restaurant empire.
“I don’t enjoy emails very much. I like talking to people directly. I think you understand people better that way,” Puck told Business Insider earlier this year.

The Canva CEO isn’t against using email, but limits it to protect her personal time.
“I don’t have email or Slack on my phone,” Perkins said on a podcast last year. “When I shut my laptop, I actually tune out.”
She said she remains reachable through emergency calls or pages, but otherwise tries to separate work from downtime.
