Hallo, I just installed exchange 2013 to update exchange 2010. I have everything made it to work correctly and I am in the last step to go live the new server. But I can not configure outlook 2016 to connect to new exchange 2013. From OWA everything is working I try almost all the google answer but no luck. I have to mention that Exchange 2010 is productive in my environment that's why I need to first be 100% sure that exchange 2013 will work and then to remove it. Does anyone else has the same problem.
