Send Store Preview & Use Images in Microsoft Teams

This guide shows you how to send a store preview (a live snapshot of a SharePoint or OneDrive file) in a Microsoft Teams chat or channel, and how to use images effectively within Teams. You’ll learn the quickest way to share a file so teammates can see it without leaving the conversation, plus how to insert images directly into your messages.

What You’ll Need

• A Microsoft Teams desktop app (Windows or Mac) or the web version at teams.microsoft.com.
• A file already uploaded to OneDrive, SharePoint, or a Teams channel that you want to preview.
• An image file (PNG, JPG, GIF, etc.) stored locally or in Teams.
• Appropriate permissions to view and share the file (usually automatic if you own it or have edit access).

Step-by-Step

1. Open the target chat or channel. Go to the conversation where you want to share the file. For a channel, select the channel from the left sidebar.
2. Click the paperclip icon (Attach) below the message box. In the menu that appears, choose Recent, OneDrive, SharePoint, or Upload from this device.
3. Select the file. Browse to the file you want to share. If it’s in a channel, you can also click the Files tab at the top of the channel, hover over the file, and click the three dots (…) to choose Copy link or Share.
4. Choose how to send it. After attaching, you’ll see two options: Share as a link (creates a clickable link) or Share as a copy (uploads a copy). For a live preview, choose Share as a link – this shows a thumbnail preview in the message.
5. Add a message (optional) and press Enter. The recipient sees a small preview card with the file name and icon. Clicking it opens the file in Teams or the web app.
6. To use an image in a message: Simply drag and drop an image file directly into the compose box, or click the image icon (if available) in the formatting toolbar. You can also paste (Ctrl+V / Cmd+V) an image copied from your clipboard.
7. For a channel post with an image: Click the Format button (pencil icon) under the message box, then use the image icon in the toolbar to insert an image from your device or from OneDrive.
8. To view a preview before sending: Hover over the attached file in the compose box. A small preview window appears. Click the preview to expand it, then close it to return.
9. To send a preview of a file that’s already in a channel: Go to the Files tab, hover over the file, click the three dots, and select Copy link. Then paste the link into the message box – Teams automatically converts it to a preview card.

Common Mistakes

• Choosing “Share as a copyâ€� instead of “Share as a linkâ€� – this uploads a duplicate and doesn’t show a live preview; edits won’t sync.
• Dragging a file into the message box but not waiting for the preview to load – sometimes the preview takes a few seconds; sending immediately still works but the recipient may see a plain link.
• Using an image that’s too large – Teams may compress it, but very large files can fail to upload. Stick to under 10 MB for best results.
• Forgetting to set permissions – if the file is in a private channel, recipients outside that channel won’t see the preview, only an error.
• Pasting a link from a browser instead of using the Attach button – sometimes pasted links don’t generate a preview card if the link is not a direct Teams link.

Tips

• Use the “Recentâ€� tab in the attach menu for files you’ve recently opened – it’s faster than browsing.
• For images you want to annotate, use the Edit button on the preview card before sending (if available) – you can draw or add text.
• In a channel, use the “Filesâ€� tab to share a link – this keeps the file in the same location and avoids duplicates.
• If you want to show a preview of a PDF or Office document, ensure the file is in OneDrive or SharePoint – local files only upload as a copy.
• Use the “@mentionâ€� in the message to notify specific people about the shared file.

Troubleshooting

• Preview doesn’t appear: Wait a few seconds; if it still doesn’t show, try removing the attachment and re-adding it. If the file is large (over 50 MB), the preview may not generate – share a link instead.
• “You don’t have accessâ€� error: Check the file’s sharing settings. Right-click the file in OneDrive or SharePoint, select Manage access, and ensure the people in the chat have permission.
• Image upload fails: Reduce the image size (e.g., screenshot or resize) and try again. Also check your internet connection.
• Preview shows a blank box: This may happen with certain file types (e.g., .zip, .exe). Teams only previews Office documents, PDFs, and common image formats.
• Pasted link doesn’t convert to a preview: Make sure the link is a direct link to the file (not a sharing link that requires a login). Right-click the file in OneDrive and select Copy link to get the correct one.

Frequently Asked Questions

1. Can I send a preview of a file that’s on my local computer?
   No – local files are uploaded as a copy, not a live preview. To get a preview, upload the file to OneDrive or SharePoint first, then share the link.
2. Why does my preview show a download icon instead of a thumbnail?
   That happens when Teams can’t generate a thumbnail (e.g., for unsupported formats). The recipient can still click to download or open.
3. Can I edit the file directly from the preview?
   Yes – if it’s an Office document, the recipient can click the “Edit� button in the preview to open it in the corresponding app (Word, Excel, etc.).
4. How do I send an image that’s already in a channel?
   Go to the channel’s Files tab, find the image, click the three dots, choose Copy link, then paste it into the message. Or download it and re-upload as an attachment.
5. Does the preview update if I edit the file?
   Yes – if you share a link (not a copy), any changes saved to the original file are reflected in the preview after a short delay.
6. Can I preview a file in a private chat?
   Yes, as long as the file is in OneDrive or SharePoint and you have permission to share it. The preview works the same as in channels.
