Share files in Microsoft Teams

Files shared in Teams are stored in SharePoint or OneDrive, so everyone edits the same copy in real time.

Share in a channel

1. Open the channel and select the Files tab.
2. Select Upload to add a file from your computer, or New to create one in place.
3. Right-click the file and choose Copy link — paste the link in a channel message to notify the team.
4. To set permissions, select the file → Open in SharePoint → Share → choose who can view or edit.

Share in a chat

1. Open the chat and select the paperclip icon in the message bar.
2. Choose Upload from my computer or Browse Teams and Channels to attach an existing Teams file.
3. Send the message — the recipient gets a co-editing link automatically.

Tips

• Use @mention a file (type @ then the file name) to highlight it in a message.
• Files tab shows the full version history — select the file → ... → Version history to restore an earlier copy.
• Do not use Download then email — edits to the downloaded copy will not sync back.
