Older desktop versions of Outlook (2016 and earlier) use an older browser engine and cannot run the standard add-in. We provide a separate version built for those clients. If you are on Outlook 2019 or newer, Outlook on the web, or the new Outlook for Windows, use the standard download above.
Download the Outlook 2016 manifest and install it the same way: in Outlook go to File, then Manage Add-ins, then add a custom add-in from file.
One difference on this version: you pick the files to encrypt from your computer in the MySecureSend panel, rather than attaching them to the email first. Attachments already on the email are left as they are.
