• Microsoft is removing the built-in “Send to Kindle” option in Microsoft Word that let you send .doc or .docx files directly to your Amazon Kindle library.
• The feature will be retired after February 2026, likely rolled out in stages and fully removed by early March 2026.
• Once removed, you won’t find the option in Word’s Export/Share menus anymore.

What the feature did

Before its retirement, “Send to Kindle” allowed you to:

• Convert and send Word documents to your Kindle account straight from Word.
• Keep formatting like layout and fonts for reading on Kindle devices or apps.
• Get your document in either a Kindle-friendly reflowable ebook style or as a fixed layout.
  (Only tracked changes and comments didn’t carry over.)

What changes for users

• After the retirement date, the feature will no longer work in Word (Windows, Mac, or web).
• Microsoft says you should upload Word files to Kindle manually using Amazon’s official Send to Kindle website instead.
• Files already sent to your Kindle remain available — they’re not erased.

Why this matters

• Convenience loss: If you regularly used Word’s one-click Kindle upload, you’ll now need an extra step in your workflow.
• It reflects Microsoft’s larger effort to streamline Office and shift specialized workflows to external tools.
