Alert Message: 

Beginning at 8pm on Thursday, August 22, 2019, CUIT will perform scheduled maintenance on the ADCU Exchange email servers.  This scheduled maintenance is expected to be completed by 11pm.  Please note that this will not affect customers that have not migrated to ADCU.

During the scheduled time of this Service Alert customers may experience brief disconnects while using Outlook.  If Outlook prompts for a password or does not show new messages after the work is complete, please restart Outlook.

CUIT apologizes for any inconvenience this may cause, but this action is necessary to ensure a more reliable service.  If customers continue to experience issues after the scheduled maintenance window, please contact the CUIT Service Desk at:
