Once you’re in a chat, you can send messages that contain files, pictures, and links.
Send a link
To send a link, click Format 
below the compose box, then press Insert link 
.
Attach display text and the address, and then pick Insert, or simply copy and paste the link into the compose box and press Send 
. After you send it, the message including your link has a thumbnail image and preview, which you can dismiss if you’d prefer not see it.
Note: Teams has its own ATP Safe Links security to verify that any link that you send or receive is safe to click on. As an added layer of protection, we’ll let you know if we’ve identified a potentially unsafe link.
Include a file or picture
To embed a file or picture in a message, choose Choose file 
under the compose box. Then, you can upload an file or picture from your computer or OneDrive, or search for one from the Files tab for that channel.
In a chat conversation, select Choose file and choose your desired file or picture from your computer or OneDrive.
