This topic explains how to configure Microsoft Exchange Server 2007 so that published Free/Busy information for a mailbox is displayed for more than two months. To do this, you must configure the registry on the Exchange server that is running Resource Booking Attendant.

By default, Microsoft Office Outlook displays the Free/Busy information for a mailbox for a two-month period. If you want to display Free/Busy information for longer, you must add the Excdo\Parameters subkey to the registry, and then add the value for the period that you want to display Free/Busy information. After you make this change, restart the Internet Information Services (IIS) Admin service and the Microsoft Exchange System Attendant service.

To change the length of time that Free/Busy information is displayed for a mailbox

  1. Open Registry Editor.

  2. Expand the following subkey:

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft

  3. Right-click Microsoft, point to New, and then click Key.

  4. Type Excdo, and then press ENTER to name the new key.

  5. Right-click Excdo, point to New, and then click Key.

  6. Type Parameters, and then press ENTER to name the new subkey.

  7. Right-click Parameters, point to New, and then click DWORD Value.

  8. Type FBPublishMonth, and then press ENTER to name the new value.

  9. Right-click FBPublishMonth, and then click Modify.

  10. In the Value data box, type the number of months that you want to publish Free/Busy information. For example, if you want to publish Free/Busy data for four months, type 4 in the Value data box.

  11. Exit Registry Editor.

  12. Restart the Internet Information Services (IIS) Admin service and the Microsoft Exchange System Attendant service. To do this, open a command prompt, and then type the following commands. Press ENTER after each command.

    iisreset
