HTTP Connections Dropped after moving 14.1.2

Thanks for the response. Looking at the Exchange 2016 iapp, there is an irule with HTTP::redirect but it is the last action in the irule. Here's the irule.

priority 900
when HTTP_REQUEST {
    if { ([HTTP::uri] == "/") } {
        HTTP::redirect https://[HTTP::host]/owa/
    }
} 

I would expect F5 to update the Exchange iapp, if it were not compatible with 14.1.2, from the information in this support article it doesn't appear that there is a problem.
