Hi, I have an Exchange 2013 running on Windows Server 2012, and I got these errors after I update Windows. 1. I cannot open ECP. After I put my credentials to login, I got an error "500 Unexpected error". OWA is working fine though. 2. Error in opening Exchange Management Shell. With error mentioning that "Unable to determine the installed file version from the registry key Please help! Many thanks in advance. Below is event viewer ID error 258: |
