Resolving Certificate Error with iOS devices

iOS Certificate Resolution 

(iPhone, iPad on iOS 13.4)

If you are receiving an error with your iOS device regarding certificate authentication this is caused by the renewal of our Secure Socket Layer (SSL) Certificate.  This SSL Certificate is used to secure transmission of emails from the sending party to a receiving party.  The error will look similar to what is below.  If you have the option to Continue you can select that.  Should it fail or not connect please refer to the rest of this article for assistance.

While SSL is not required it is recommended in setup.  The issue can be resolved in a couple ways, all of which will be provided in the Table of Contents to the left.  Please make sure to follow the steps provided in order.  In order to resolve the certificate error iOS devices might receive the account will need to be removed and then added back onto the device.  This will force the trusted certificate back on and should resolve any issues.
