I upgraded exchange to 2016 and I just got it working, where with any browser, if I type: mail.mycompany.org it would redirect me to my OWA, of https://mail.mycompany.org
, but now it's not anymore.
I have tried this on multiple computers, both internally and externally.
Any idea's what's wrong? I confirmed that on my exchange server, under IIS redirect for the default site, I have the check mark checked for "redirect requests to this destination".
I get this error.
