Follow the steps below to create the Virtual Service for Outlook MAPI connectivity:

  1. In the main menu of the LoadMaster WUI, select Virtual Services.
  2. Select Add New.

  3. Enter a valid Virtual Address.
  4. Enter * (asterisk) as the Port.
    Note: If you wish to configure your Exchange 2010 environment to utilize static RPC ports as opposed to the dynamic port range realized by inputting the asterisk, you should first configure your Exchange 2010 Server. You can enter a specific port number for each Virtual Service.
    Note: Do not change the wildcard service to Layer 4 as doing so will cause inoperability.
  5. Select tcp as the Protocol.
    Note: The combination of Virtual Address, Port and Protocol must be unique within the LoadMaster.
  6. Click Add this Virtual Service.
  7. Configure the settings as shown in the following table:
