Based on the presence of specific custom properties or keywords, we aim to disable Word's default 'Save,' 'Save As,' and 'Share' options to prevent users from saving or sharing the document locally.

Question

Is it technically possible to achieve the following using Office.js in a Word add-in?

We want to add custom properties (such as document IDs and metadata) to Word documents opened via our add-in. Based on the presence of specific custom properties or keywords, we aim to disable Word's default 'Save,' 'Save As,' and 'Share' options to prevent users from saving or sharing the document locally.

Additionally, we would like to implement custom protection mechanisms through our add-in. Could you please confirm whether this functionality can be implemented and suggest best practices or limitations we should be aware of?"
