Using this policy, you can define default servers and server data for Meeting Workspaces. It is recommended that you draft this policy in a text editor and paste it into the text box in the setting. You can add up to five servers by listing them in the "Default server:" text box. Each server is defined by a pipe-delimited list, with a total of six pipes per server record. The OrganizerName field is left blank. For example: http://server1 | Friendly name for server1 | templateLCID | templateID | TemplateName | OrganizerName | http://server2 | ... and so on.
