Hi,

          $FEOWAVdirIdentity = $RoleNetBIOSName + "\OWA (Default Web Site)";
          $FEOWAVdir = get-OwaVirtualDirectory -Identity $FEOWAVdirIdentity -DomainController $RoleDomainController;

          if ($FEOWAVdir -ne $null)
          {

how can I f

Hi

Can you please provide more info?

Did you update the schema and prepare AD? Are you running any other version of Exchange in your organization?

Does the OWA directory Exist?

Hi,

Please post the answers as Edward asked, and run Get-OwaVirtualDirectory | FL Identity to ensure 'Server\OWA (Default Web Site)" already exists.

If it missing, double check in IIS manager on problematic server. Please run below command to recreate:
New-OwaVirtualDirectory -InternalUrl https://mail.contoso.com/owa -WebSiteName Default Web Site

If this issue persists, try open ADSI Edit, and navigate to "CN=owa (Default Web Site), CN=HTTP, CN=Protocols, CN=ex, CN=Servers, CN=Exchange Administrative Group (FYDIBOHF23SPDLT), CN=Administrative Groups, CN=First Organization, CN=Microsoft Exchange, CN=Services, CN=Configuration, DC=domain, DC=local", check whether there exist an object relevant to OWA. If it missed, please renew it with class "msExchOwaVirtualDirectory", also add relevant attributes to it.
Note: Do not use ADSIedit when you dont know what you are doing. Improper use can damage your Active Directory or other services beyond repair! Also recommend open an case with Microsoft to further troubleshooting.

Thanks

It was totally my bad. I had to fix my OWA and ECP Virtual directories again correctly

Thanks for sharing the feedback. Glad all is working now.
