Have you ever accidentally sent an email to everyone in your company?
Well, that's what one guy called Vince did on Wednesday, except that his company employs tens of thousands of people around the world.
Employees of the Thomson Reuters office south of St. Paul were embroiled in the email meltdown that become a major trending topic on social media under the hashtag #ReutersReplyAllGate.
As the Wall Street Journal explains, the aforementioned Vince sent an email that ended up reaching 33,000 inboxes. What then followed were hundreds of "reply all" email responses from other workers telling people to stop "replying all."
Pleas for mercy only made things worse, the newspaper notes, with employees seeing their emails slow down, although a company spokesman said all systems were still operational.
Here are some of the best tweets – and spare a thought for poor old Vince.
