Tasks

  1. Create a New Web Site for the OAB Web Distribution Virtual Directory
  2. Use the Exchange Management Shell to Remove and Re-Create the OAB Virtual Directory
  3. Add the Default Offline Address Book to the Web Distribution Point
  4. Configure SSL for Offline Address Book Distribution
  5. Create the OAB DNS Record
  6. Disable Unnecessary Services on EXCASOAB01

Create a New Web Site for the OAB Web Distribution Virtual Directory

Procedure W08-DWHE.75: To create a new Web site for the OAB Web Distribution virtual directory

  1. Logon to the OAB Web Distribution Server, EXCASOAB01, as Fabrikam\Administrator

  2. Assign an additional unique IP address to the network interface card on EXCASOAB01. This IP will be linked to the new Web site for OAB Web Distribution.

  3. Run IIS Manager, and create a new Web site on EXCASOAB01. Specify the Site name as OABDistribution. For Physical path, specify a path to an empty directory; for performance reasons, it is recommended that the OAB Web site directory be placed on a different disk than the system volume. Under Binding, Specify the IP address that was added to the server in step 2, and accept the default port of 80.

Use the Exchange Management Shell to Remove and Re-Create the OAB Virtual Directory

Procedure W08-DWHE.76: To use the Exchange Management Shell to remove and re-create the OAB virtual directory

  1. Open the Exchange Management Shell on EXCASOAB01.

  2. To make a record of the default OAB virtual directory's settings, run the following command:

      Copy Code 
    Get-OABVirtualDirectory -Identity 'OAB (Default Web Site)' | fl | Out-File -filePath 'C:\OAB_DefWS_Settings.txt'

  3. To delete the default OAB virtual directory, run the following command:

      Copy Code 
    Remove-OABVirtualDirectory -Identity 'OAB (Default Web Site)'

  4. To create a new Offline Address Book virtual directory on the new Web site, run the following command:

      Copy Code 
    New-OABVirtualDirectory -Server EXCASOAB01 -WebSiteName 'OABDistribution' -RequireSSL $true -ExternalURL 'https://oab.consolidatedmessenger.com/OAB'

Add the Default Offline Address Book to the Web Distribution Point

As a result of removing the original OAB virtual directory, the default Offline Address Book is no longer configured for web distribution. In this procedure, you will make it available for download via the new OAB virtual directory.

Procedure W08-DWHE.77: To add the default Offline Address Book to the Web distribution point

  1. On EXCASOAB01, open the Exchange Management Console, expand Organization Configuration, and then select Mailbox.

  2. On the Offline Address Book tab, right-click the Default Offline Address Book and select Properties.

  3. On the Distribution tab, select Enable Web-based distribution, and then specify the OAB distribution point on EXCASOAB01.

Configure SSL for Offline Address Book Distribution

You must use a valid SSL certificate that is created by a certification authority (CA) that is trusted by the Microsoft Office Outlook 2007 client computer's operating systems. For more information about how to install a SSL certificate, see the article How to Setup SSL on IIS7 on the Microsoft Internet Information Services (IIS) Web site.

Procedure W08-DWHE.78: To configure SSL for Offline Address Book Distribution

  1. Request, install, and bind an SSL certificate for the OABDistribution Web site. For the purposes of this reference architecture, the common name for this certificate should be oab.consolidatedmessenger.com

Create the OAB DNS Record

Procedure W08-DWHE.79: To create the OAB DNS record

  1. Open the DNS MMC on DNS01.

  2. Create a new host (A) named oab for the forward lookup zone consolidatedmessenger.com. During the process, you will type the external interface (static) IP address for the new Web site on EXCASOAB01 which contains the /OAB virtual directory.

    Note:
    While CAS servers can be load balanced, Hosted Messaging and Collaboration version 4.5 has incorporated the concept of OAS CAS Pool to support high availability. Instead of load balancing the OAB servers, you can add different OAB servers to the OAB CAS Pool by using provisioning API. See later section about how to set OAB CAS Pool and adding servers to the pool.

Disable Unnecessary Services on EXCASOAB01

To make EXCASOAB01 a dedicated OAB Web Distribution server, other services supported by Client Access server role must be disabled.

The following provides procedures to disable POP and IMAP service, remove OWA virtual directory, and stop the default Web site on EXCASOAB01.

Procedure W08-DWHE.80: To disable POP and IMAP services on EXCASOAB01

  1. Open the Exchange Management Shell on EXCASOAB01.

  2. Run the following commands:

      Copy Code 
    Set-service msExchangePOP3 -startuptype disabled
Set-service msExchangeIMAP4 -startuptype disabled

Procedure W08-DWHE.81: To remove the Outlook Web Access Virtual Directory

  1. To make a record of your current OWA virtual directory settings, run the following command from the Exchange Management Shell on EXCASOAB01:

      Copy Code 
    Get-OwaVirtualDirectory -identity 'EXCASOAB01\owa (Default Web Site)' | fl | Out-File -filePath 'C:\owa_DefWS_Settings.txt'

  2. Remove the old AutoDiscover virtual directory by running the following command in the Exchange Management Shell:

      Copy Code 
    Remove-OwaVirtualDirectory -identity 'EXCASOAB01\owa (Default Web Site)'

Procedure W08-DWHE.82: To stop the Default Web Site on EXCASOAB01
