State government email servers were down Monday morning, officials said, urging Minnesotans to pick up the phone to conduct state business.

MN.IT, the state's information-technology agency, said the problem was not caused by a security breach. The state has experienced cyber attacks on computer servers for the state's judicial branch.

Monday's email outage was caused by an unspecified "Microsoft change to the email system," according to a news release. A MN.IT spokeswoman did not provide an estimate for when email would be restored.

[Update: State email systems were restored by 5 p.m. Monday.]
