Pros: It's a great way to communicate with a team or group of people. You can have multiple chats going at the same time, and it's easy to find past conversations. The interface is clean and easy to use. You can easily share files, images, and links. It integrates well with other Microsoft products, like Outlook and Office 365. Cons: Not everyone is familiar with it yet, so you may have to explain how it works to some people.
