Creating Additional OWA Virtual Directory with its own Executables & .Dll files

Creating Multiple OWA Virtual Directories with Same IP on Different Port Exchange2010 - Part 2

This post is in continuation to our previous post Creating Multiple OWA Virtual Directories with Same IP on Different Port- Exchange . While working on the same requirement I found out that the last method may work fine for some but in case you have some scripts attached to the OWA .aspx files or .dll's then the same may reflect in the working of the new virtual directory too. In my case that was not acceptable.

Here, we will assign the new VD a new Physical Path and its own set of executable and dll files.

Note: Copy the contents of a same versioned Exchange 2010 from a new setup (location mentioned below).

IS Activities

 1. Add DNS entries:

      Create a new A Host record with a new URL for the existing IP.

2. Add NEW Website in IIS

     Open IIS and add a new website-

3. Copy the contents of the Folders from a new setup:

C:\Program Files\Microsoft\Exchange Server\V14\ClientAccess\Owa

C:\Program Files\Microsoft\Exchange Server\V14\ClientAccess\ecp

And paste then to the following location

C:\Program Files\Microsoft\Exchange Server\(mail2)\ClientAccess\Owa

C:\Program Files\Microsoft\Exchange Server\(mail2)\ClientAccess\ecp

4.  In IIS change the location of the ISAPI filter of the new VD to the new location of the owaauth.dll file. In this case, C:\Program Files\Microsoft\Exchange Server\mail2\ClientAccess\Owa\auth\owaauth.dll

5. Change Virtual Directory Path of the following sub-folders too-

Exchange- C:\Program Files\Microsoft\Exchange Server\mail2\ClientAccess\Owa

Exchweb- C:\Program Files\Microsoft\Exchange Server\mail2\ClientAccess\Owa

Public- C:\Program Files\Microsoft\Exchange Server\mail2\ClientAccess\Owa

Now, Reset IIS and things should work fine.
