Add a Range API for Outlook add-ins

Word add-ins provide the Word.Range API, which allows precise manipulation of document content (selection, insertion, replacement, formatting).

Outlook add-ins currently lack an equivalent API, making fine-grained interaction with the message body difficult or impossible.

We propose adding a Range-like API for Outlook add-ins to enable:

• Access to the current selection in the message body

• Insert or replace text at a specific position

This would significantly improve advanced authoring, productivity, and AI-assisted scenarios in Outlook.

Example (conceptual)

const range = Outlook.context.mailbox.item.getSelectedRange();
range.insertText("Hello world", Outlook.InsertLocation.replace);
