We have exchange 2016. after renewing ssl cert and the old one expired..... all of a sudden all apple devices 20 - 30 devices (iPhones and iPads) cannot connect to server to retrieve emails with the apple mail app. All android devices are fine. Outlook web app on apple devices works just fine. I am completely Stump on this. I have tried on my iPhone12: resetting network settings, Reboot phone, toggled airport mode, removed account and added back, removed the mail app and reinstalled it I cant be the only one that this has happened to, any suggestions or point me in the right direction to look/trouble shoot this problem. Thank you for any help you can provide.

    Hi @Yuki Sun-MSFT ,

    Yes I have resolved the issue. We use a Proxy server with ARR installed. What I failed to do was bind the https on the default website to the new cert. After completing this all iPhones and iPads were able to connect using the default apple mail app
