Microsoft Word is not just an application for creating documents. It is the central app for organizations to "create and circulate formal documents," encompassing co-authoring, comments, track changes, templates, PDF export, and accessibility checks.
License Positioning
| Item | M365 E3 | M365 E5 |
|---|---|---|
| Word Web / Mobile | Available | Available |
| Word Desktop | Available | Available |
| Microsoft Copilot in Word | Separate Copilot license required | Separate Copilot license required |
While Word can be used with the base E3/E5 licenses alone, Microsoft Copilot within Word requires a separate license.
When Should You Use It?
Word is best suited for documents where you need to preserve not just the content itself, but also revisions, comments, layout, and pre-approval edits.
Drafts for approval requests or internal briefing materials
Procedure manuals, user guidelines, and proposed regulations
Reviews of contracts and specifications
Official versions of meeting minutes
Documents to be distributed as PDFs
For simple notes, Loop or OneNote are more natural; for list management, Lists; and for handling numerical data simultaneously, Excel.
Try It First: Edit Just One Line Using Track Changes
Create a test Word document
Go to Review -> Track Changes and turn it on
Rewrite a single sentence
Add a single comment
Check this
Verify that your edits remain not as a simple overwrite, but as a record showing who changed what.
Try modifying one location
Open the same document in the browser version of Word and check if the same track changes are visible. This gives you a feel for seamlessly moving between the desktop and web versions.
Prompts to Try If You Have Access to Copilot
この文書を「目的 / 現状 / 課題 / 次のアクション」の4見出しに整理してください。 元の事実は追加・削除せず、推測は「推測」と明示してください。 箇条書きを使い、担当者が次に何をすればよいか分かる形にしてください。
The key is not to just end with "make it look nice," but rather to:preserve facts, separate assumptions, and specify the output structure.
Checking the Existence of a Word File via PowerShell
This is a safe example that first checks if the file exists before automatically editing the body text.
$path = "$env:USERPROFILEDocumentssample.docx"
if (Test-Path -LiteralPath $path) {
Get-Item -LiteralPath $path |
Select-Object Name, Length, LastWriteTime
} else {
Write-Host "[NOT FOUND] $path"
}
As a best practice, always test automated processing of Office files on a copy rather than writing directly to production documents.
For Professional Use
When collaborating on Word documents within a team, storing them in OneDrive or SharePoint and co-authoring is much easier to manage than multiplying versions via email attachments.
Additionally, in organizations handling confidential information, Microsoft Purview Information Protection sensitivity labels may be displayed. Do not remove labels on your own judgment; follow organizational policies.

Word's role becomes much clearer when viewed not as an app for "writing text," but as an app for safely collaborating on organizational documents and developing them through to their final version.
