The Outlook add-in

Installing it inside Outlook, and what is still unverified.

Not yet verified on a live Microsoft 365 tenant. Microsoft’s own manifest validator passes, the hosting meets their requirements, and the logic is tested against a simulated Office environment — but it has not yet run inside real Outlook. If you use Gmail or Outlook on the web, the browser plugin is the tested route; for everything else, the desktop application is.

Installing

  1. Open Outlook on the web → Settings (gear) → General → Manage add-ins.
  2. Choose My add-ins → Add a custom add-in → Add from URL.
  3. Paste https://anuumail.com/manifest.xml and accept the warning about a custom add-in.

A ProtectMyMail button appears when you read a message, and a Protect button when you write one.

What it does that the others cannot

Outlook hands an add-in the real message, including its internet headers. So this one reads the actual SPF, DKIM and DMARC results rather than inferring anything from what is on the screen.

If the pane is blank or stuck

It checks, before anything else, whether this Outlook build supports the cryptography it needs. If it does not, it says so plainly along with the version you are on. If you see that, please report it — it is the one finding that would need a real change.

Opening https://anuumail.com/taskpane.html directly in a browser will show a message saying it needs Outlook. That is expected, and means the hosting is working.
