## What is MicrosoftPreview?

Generates page previews for Microsoft products.

## How to identify it

Look for the MicrosoftPreview identifier in a request’s User-Agent. This is a name match, not identity verification. Version strings may change.

## How to check identity

Use Microsoft’s documented bot verification procedure and current IP information; do not trust the User-Agent alone.

## Access and robots.txt

robots.txt behavior is not established by the linked source. Confirm the current policy before relying on an opt-out.

## What it means in your analytics

A preview retrieval can occur without a click through to your site.

## Useful measures

Shared URLs; Image responses; Preview fetch errors.

## What to check next

Inspect preview metadata and the response from the exact URL being shared.
