Office Web Add-In
The Office Web Add-In makes primedocs available in Word, Excel and PowerPoint in the browser (Microsoft 365 / office.com). It offers the same task pane as the Office Desktop Add-In.
The Web and Desktop Add-In are technically identical: they use the same manifest and the same generation endpoint. An Office.js add-in runs with the same manifest both in the Office desktop applications (Windows, macOS) and in Office in the browser.
Installation
Installation is identical to the Desktop Add-In – configuration in the primedocs.config, generation of the manifest and distribution via the Microsoft 365 Admin Center. You can find the full instructions here:
➜ Office Desktop Add-In — Installation
After distribution via the Microsoft 365 Admin Center, the add-in is automatically also available in Office in the browser; a separate step is not required.
Prerequisites
- Microsoft 365 with Office in the browser (office.com).
- Reachability of the primedocs web application via HTTPS.
- Distribution of the add-in via the Microsoft 365 Admin Center.
For the new Outlook in the browser, there is a separate add-in with its own manifest: Outlook (New).
