Dear all

During install Exchange 2013 through Powershell on Server 2012 I got this error in Mailbox role: Client Access service :

 The following error was generated when "$error.Clear();
          $BEVdirIdentity = $RoleNetBIOSName + "\OWA (Exchange Back End)";
          new-OwaVirtualDirectory -Role Mailbox -WebSiteName "Exchange Back End" -DomainController $RoleDomainController
;
          set-OwaVirtualdirectory -Identity $BEVdirIdentity -FormsAuthentication:$false -WindowsAuthentication:$true;
        " was run: "An error occurred while creating the IIS virtual directory 'IIS://MONAMBX2.mona.local/W3SVC/2/ROOT/o
wa' on 'MONAMBX2'.".

     The following error was generated when "$error.Clear();
          $BEVdirIdentity = $RoleNetBIOSName + "\OWA (Exchange Back End)";
          new-OwaVirtualDirectory -Role Mailbox -WebSiteName "Exchange Back End" -DomainController $RoleDomainController
;
          set-OwaVirtualdirectory -Identity $BEVdirIdentity -FormsAuthentication:$false -WindowsAuthentication:$true;
        " was run: "The operation couldn't be performed because object 'MONAMBX2\OWA (Exchange Back End)' couldn't be fo
und on 'MonaDc1.mona.local'.".

Any advice please !!

I can't answer your question but I had a similar issue when I was trying to move our mailbox database off the C: drive.  Our environment still has an Exchange 2007 server in it and when I was trying to move the database on the 2013 server, I would get error messages saying the database does not exist.  It seemed like it was trying to move the database on the 2007 server from the similar error messages that I was getting.  To get around it, I deleted the database and created a new one on the drive where we wanted it.

I discovered this when I was configuring the Antispam settings.  I deleted our 2007 settings, added them to the 2013 shell, the settings appeared on our 2007 server.  The shell on 2013 was making changes to 2007.

I'm not sure if there is a "Get|Set or New" command that I/we should be using when this happens.  Or maybe my issues will be fixed if I just remove the Exchange 2007 server?  I'm not ready to do that yet because I can't configure the spam filtering on 2013 yet with its shell not being able to make the changes that we need.

I don't know if your environment is in coexistence mode like mine.

Hopefully someone else out there has an answer or can tell us when/how the shell can make the appropriate changes to the 2013 server.  Does this happen after the 2007 server is removed?
