longacre writes: "Just a few months after the New York City Dept. of Education shelled out over $1 million on iPads for teachers, the agency has stopped accepting new users on its Microsoft Exchange ActiveSync server as it is "operating near its resource limits" due to an influx of iOS and Android devices. A memo from the deputy CTO warned, "Our Exchange system is currently operating near its resource limits and in order to prevent Exchange from exceeding these limits, we need to take action to prevent any more of these devices from being configured to receive email. As of Thursday, November 10th no additional users will be allowed to receive email via NYCDOE's Exchange ActiveSync." Existing setups will continue to operate, and students will not be affected."
