Greetings, When navigating to server configuration and CAS, I get the below pop error message and don't know what I should do to resolve the error, please help! The following warnings were reported while loading topology information: Warning: Object MyServer\Exchange(Default Web Site) has been corrupted and it is in an inconsistent state. The following validation errors have occurred: Warning: "DigestAuthentication" only applies to Exchange 2007 virtual directories van

Hi Van, If you run the cmdlet Get-OwaVirtualDirectory , the same error? Can you open OWA successfully? If you enter the URL Https://domain/exchange, is there any error message? Please try to delete the Exchange Virtual directory, and create a new one. 1, Remove-OwaVirtualDirectory "MyServer\Exchange (Default Web Site)" 2, New-OwaVirtualDirectory -Name Exchange -OwaVersion Exchange2003or2000 -VirtualDirectoryType Mailboxes -WebsiteName "Default Web Site"Frank Wang

That did the trick, thank you so much!van
