  • Question

  • Hi All,

    I would like to know how can I switch email encryption settings in Outlook 2016, so that it can start using AES256 encrpytion algorithm instead of 3DES?

    Thanks.

  • Hi,

    You may try the following steps and see whether this is what you want:

    1. In Outlook, click File > Options > Trust Center > Trust Center Settings.
    2. In the "Trust Center" window that appears, select E-mail Security.
    3. Under the "Encrypted E-mail" heading, click the Settings button.
    4. In the "Change Security Settings" dialog than opens, under the "Certificates and Algorithms" heading, click the "Encryption Algorithm" drop-down menu. Set it to AES (256-bit) if it isn't already set to that.

    Hope this helps.

    Regards,
