Images that don't meet platform requirements may be cropped incorrectly, rejected, or displayed at poor quality.

Each platform has different specifications. Make sure your image meets Microsoft Teams's requirements shown below.

Open Graph tags control how your content appears when shared on social media platforms like Facebook, Twitter, and LinkedIn.

Missing or incorrect tags can result in broken previews, missing images, or unappealing shares that reduce click-through rates.

When you share a link on Microsoft Teams, it sends a server-side request, not a browser, to fetch the page's HTML and read the meta tags. This is the request it makes.

After reading the meta tags, Microsoft Teams makes a separate request to download the image. Some platforms use a different User-Agent or Accept header for images.
