Outlook Web Access (OWA) KIT mailbox

You do not need to configure a mail program for Outlook Web Access. Access is via the web browser and is therefore easy and possible from anywhere.

 

Note: The S/MIME control for encrypting, decrypting and digitally signing e-mails is only supported by certain browsers under Windows under certain conditions.
