ScanHawk for Microsoft 365

Checks where a link really goes before you click — in Outlook, Word, Excel and PowerPoint.

This is the add-in's hosting origin. Office loads the task pane from here; there is nothing to sign in to and nothing else to browse. If you are installing the add-in, you need one of the manifest files below.

Manifests

Pick by which Office you have; see the notes for which file reaches what.
FileReaches
manifest.json Outlook, Word, Excel and PowerPoint in one install — Microsoft 365 subscription builds and Office on the web. The one to use unless the next two apply.
manifest.xml Outlook only, on any build including perpetual Office.
manifest.office.xml Word, Excel, PowerPoint and OneNote on the web, on any build including perpetual Office.

Install for yourself

  1. Download the manifest file you need from the table above.
  2. Outlook: open aka.ms/olksideload, choose My add-ins, then Add a custom add-inAdd from File, and pick the file. It appears in Outlook on the web and the Outlook desktop app.
  3. Word, Excel or PowerPoint: on the Home tab choose Add-insMore Add-insMy Add-insUpload My Add-in, and pick the file.

Custom add-ins are a Microsoft 365 work or school feature; an administrator can also disable them. If the option is missing, that is why.

What leaves the mailbox or the file

For each link: its address and the visible text of that link. Nothing else — no message text, subject, sender or cell values. The full statement is in the ScanHawk Privacy Policy, section 5.
