Encryption and Signing of Emails

It is possible to encrypt and sign emails within the Outlook-Add-In.

To send signed and/or encrypted emails, you must have booked email encryption in the Control Panel. In addition, a certificate must be available for each user who wants to use the signing and encryption functions.


Emails which are not routed through one of our relay servers are not signed or encrypted.

Further information on setting up the email encryption and ordering the certificates can be found under Email Encryption in the Control Panel manual.
