A system problem has caused some devices that use ActiveSync to retrieve Exchange email and calendars to stop working. To resolve this issue on your device, iOS users should re-enter their password within the account settings and Android users should force a sync.
iOS: Settings > Mail > Accounts > Exchange > Account
Android: Settings > Accounts > Microsoft Exchange ActiveSync > your-account > Settings > Sync now
