  • Email - Exchange

    On July 9th and 11th, between the hours of 3 a.m. and 5 a.m., OS patches will be applied to our Exchange environment.  Because the servers are redundant, downtime should be limited to a few minutes between the hours of 3 a.m. and 5 a.m. each day.

    Once systems have been patched, users may be prompted to enter a password to re-establish server connections.

    CUIT apologizes for any inconvenience this may cause, but this action is necessary to ensure a more reliable service.  If clients continue to experience issues after the service-interruption hours, please contact the CUIT Helpdesk at:
