# Office Add-in

The **Office Add-in** section allows you to configure how Microsoft Office applications (Word, Excel, PowerPoint) behave when working with PROTECT-encrypted files. These settings help enforce classification, control sharing behaviour, and ensure files remain protected while being edited.

**To configure Office Add-in:**

1. Go to **PROTECT > Office Add-in**.
2. Configure the following:

<table data-header-hidden><thead><tr><th width="213"></th><th></th></tr></thead><tbody><tr><td><strong>Display Classifications</strong></td><td>Enable this if you want Office apps to show Office’s built-in classification labels (such as Public, Internal, or Confidential) inside Office documents.</td></tr><tr><td><strong>Force Classifications</strong></td><td>Enable this if you require users to choose a classification before saving a file.</td></tr><tr><td><strong>Watermark</strong></td><td>Select in which part of the Office document (header, body, footer) to apply a watermark to visually reinforce sensitivity.<br><strong>Example:</strong> <code>body</code> (adds watermark text in the body of the document).</td></tr><tr><td><strong>Watermark Align</strong></td><td>Select where to place the watermark (centre, left, right).</td></tr><tr><td><strong>Disable Auto Save</strong></td><td>Enable this if you want to restrict Office from automatically saving changes to encrypted documents.</td></tr><tr><td><strong>Disable Connected Services</strong></td><td>Enable this to disable cloud services such as OneDrive, SharePoint sync, and other cloud services in Office to prevent unintentional upload of sensitive files.</td></tr><tr><td><strong>Disable Share</strong></td><td>Enable this to prevent users from sharing files using Office’s Share button. Users must share files using approved PROTECT sharing options instead.</td></tr><tr><td><strong>Blocked Printers</strong></td><td>Select the virtual or software-based printers that PROTECT should block. When selected, users will be blocked from printing protected files using these printer types, including options such as OneNote, XPS, Print to PDF, generic PDF printers, and third-party tools like Foxit, doPDF, Nitro, or Bluebeam. This helps stop users from creating unprotected copies of sensitive files through virtual printing.</td></tr></tbody></table>

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.guardware.com/protect/reports-and-configs/office-add-in.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
