Microsoft is offering companies a new antidote to one of the most troublesome viral reactions in the workplace. The new “Reply All Storm Protection” for Exchange Online on Office 365 will block replies to an email thread when at least 10 reply-all messages have been sent to more than 5,000 recipients within 60 minutes.

“We’re already seeing the first version of the feature successfully reduce the impact of reply all storms within Microsoft (humans still behave like humans no matter which company they work for ;) and believe it will also benefit many other organizations as well,” the Exchange team writes in a post introducing the feature.

In other email news, the company is preparing a text prediction feature for Outlook on the web that will predict what someone is typing and let them press the tab key to accept the text, similar to an existing feature in Google’s Gmail. This feature is due for release later this month, according to a Microsoft product roadmap.
