Micrososft Teams

Share your opinion, and your personality. Send gifs, stickers, and emojis in a group chat or in one-to-one messages.
Instantly go from group chat to video conference with the touch of a button. Teams of 10 or 10,000 can meet in one place, no matter how many places they’re in.
Never yell “who just joined?!” ever again. Use Teams calling, Phone System, Calling Plan, or Direct Routing to take the stress out of conference calls.
Never do that frantic, searching-for-files thing ever again. In Teams you can access, share, and edit Word docs, PowerPoint, and Excel files in real time.
