PEC Security protocols and requirements Print

  • 0

The PEC boxes use the TLS 1.2 communication protocol for the secure exchange of information between PEC boxes. This protocol requires that the versions of the programs used to access the PEC service be recent and updated. Therefore if you are experiencing access problems on PEC accounts from your email client, make sure it is up to date and compatible with TLS 1.2

The update to the TLS 1.2 protocol is requested by the Agency for Digital Italy to all certified mail operators.

On Windows 7 computers, Outlook does not support TLS 1.2. Consequently, by connecting to your PEC via Outlook client, you may see an error message.
