Occasional Visitor

Experiencing a stange issue after CU 12 . 

 

Can connect to the Exchange  server [Version 15.2 ‎(Build 1118.7)‎ ]  via ECP/ OWA but new profile 

attempts from Outlook clients fail and generate the below ASP error in the logs . 

The origianl update (GUI based) failed with an access to webconfig file. The second, CLi /update unattended updates passed off OK. I have seen solutions that have meant copying and replacing web.config in inetpublishing  , done , and the two sharedwebconfig locations withing exchange , done . 

Rebuilt the OAB ,  Remade IIS virtual directories and also autodiscover directory (Remove-AutodiscoverVirtualDirectory  ) , checked and remade the DNS records. Error below. Any advice greatfully recieved.
