Managing the Address Book Server from the Command Line

You can manage the Address Book Server by running ABServer.exe from a command prompt. You can modify the environment path system variable to include the location of ABServer.exe (%programfiles%\Microsoft Office Communications Server 2007\Server\Core), or you can run the tool directly from the Office Communications Server Address Book directory.

Table 6 shows valid command switches and arguments.
