Microsoft now protects Office 365 users against 'reply all' email storms


Microsoft might just save you the next time a less-than-attentive coworker starts a “reply all” email storm. It’s now rolling out (via ZDNet) an Exchange feature that protects Office 365 users worldwide against those barrages of unwanted messages. It’ll initially help large companies by blocking replies if there are 10 “reply all” messages sent to over 5,000 people within an hour. If that happens, the system will block subsequent replies for four hours and tell users to calm down.The company hopes to tweak the feature so that it can accommodate smaller organizations, let administrators customize the defense mechanism and send notifications if a storm arrives.
