In September 2016, Team Services will be ending support for Internet Explorer 9 and 10. If you use Internet Explorer 9 or 10 to connect to Team Services, you will notice a new banner reminding you that support will end in September. Although we will not explicitly block IE9 and 10, you may see a degraded or broken experience starting in September.
You can upgrade to IE11 or use one of our other supported browsers (the most recent version of Edge, Firefox, or Chrome). You can find the current supportability of Internet Explorer versions for your operating system here.
For those using on-premises TFS, our next major version will also no longer support Internet Explorer 9 and 10.
