Publish Free/Busy Information for More Than Two Months in Exchange 2010
Applies to: Exchange Server 2010 SP3, Exchange Server 2010 SP2
This topic explains how to configure Microsoft Exchange Server 2010 so that published Free/Busy information for a mailbox is displayed for more than a two-month period. To do this, you must configure the registry on the server that is running both Microsoft Exchange and 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 a longer period, you must add the Excdo\Parameters subkey to the registry, and then add the value for the period in which 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 amount of Free/Busy information that is displayed for mailboxes
Start Registry Editor.
Expand the following subkey:
Right-click Microsoft, point to New, and then click Key.
Type Excdo, and then press ENTER to name the new key.
Right-click Excdo, point to New, and then click Key.
Type Parameters, and then press ENTER to name the new subkey.
Right-click Parameters, point to New, and then click DWORD (32-bit) Value.
Type FBPublishMonths, and then press ENTER to name the new value.
Right-click FBPublishMonths, and then click Modify.
Click Decimal. Then, in the Value data box, type the number of months for which 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.
Click OK, and then exit Registry Editor.
Restart the IIS Admin service and the Microsoft Exchange System Attendant service. To do this, type the following commands at a command prompt, and then press ENTER after each command:
net stop msexchangesa && net start msexchangesa
