Office Chat is designed to work with the current or the immediately preceding versions of Internet Explorer, Mozilla Firefox, and with the latest version of Google Chrome and Safari. However, for the best experience when you use Office Chat, we recommend that you always use the latest version of the browser in question.
Firefox and Chrome are both designed to stream updates to your devices every six weeks. Many common problems with these browsers are resolved in each update and we take every effort to test and support the latest version.
Note: Beta versions of web browsers are not supported, but they are quickly added to the supported list after they’re formally released.
