+ "Outlook": "<ol><li><p>Adding the add-on:</p><ul><li><i>Note: PostGuard for Outlook only works in <q>New Outlook</q> and Outlook on the web. Classic Outlook is not supported.</i></li><li>Download the <a href=\"/downloads/postguard-outlook-manifest.xml\" download=\"manifest.xml\"><q>manifest.xml</q></a> file and save it somewhere you can find it again.</li><li>Open <a href=\"https://aka.ms/olksideload\" target=\"_blank\" rel=\"noopener noreferrer\">aka.ms/olksideload</a> in your browser.</li><li>Click <q>My add-ins</q>.</li><li>Under <q>Custom Add-ins</q>, click <q>Add a custom add-in</q>, then <q>Add from file...</q>. <i>If you do not see this option, your organization probably does not allow custom add-ins to be installed. Please contact your administrator.</i></li><li>Select the <q>manifest.xml</q> file you just downloaded and confirm to install.</li><li>Restart Outlook (close and reopen the desktop client, or refresh the browser tab if you are using Outlook on the web) to complete the activation of the add-in.</li></ul></li><li> Now, when you compose a new mail message, the PostGuard add-in is available from the <q>Apps</q> menu in the Outlook ribbon. <b>Note:</b> Outlook currently lists custom add-ins under the <q>Apps</q> menu rather than as a dedicated ribbon button — click <q>Apps</q> in the ribbon, then select <q>PostGuard Add-in</q> to open it. The add-in contains a button called <q>Send encrypted Email</q>. When clicking, it will encrypt and send the message to all recipients. Each recipient needs to use the Yivi app to prove that (s)he really possesses the email address that you used. Also, a copy of the sent mail is stored in the folder <q>PostGuard Sent Items</q> as a draft email (currently, Microsoft only allows to create messages as a draft). </li><li> After receiving a PostGuard encrypted email, the email can be decrypted by opening the message, clicking <q>Apps</q> in the Outlook ribbon, selecting <q>PostGuard Add-in</q>, and then clicking the <q>Decrypt Email</q> button. </li><li><p>What to expect when sending or decrypting:</p><ul><li><b>Security prompts are normal.</b> When you send or decrypt a message, Outlook opens a small <q>PostGuard wants to open a dialog</q> window. This is a standard Outlook security prompt for any add-in that opens a dialog — click <q>Allow</q> (or <q>OK</q>) to continue. The Yivi signing prompt that follows is also part of the standard process; it is how PostGuard verifies your identity before encrypting or decrypting.</li><li><b>If nothing happens after clicking the button</b>, your browser or Outlook is likely blocking pop-ups for the add-in dialog. Allow pop-ups for <code>outlook.office.com</code> (web) or for the PostGuard add-in domain (desktop), then try again. In most browsers you can do this from the pop-up icon that appears in the address bar after the click is blocked.</li></ul></li></ol>",
