Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.

The Microsoft Outlook client allows a user to specify how many months of free/busy data should be published on the server, and how often (in minutes) to update the information on the server. The two methods of deploying these values are:
  • Group Policy or Local Machine Policy
  • Deploy registry values manually or with a script

With Microsoft Outlook 2000 and with later versions, a Group Policy or a Local Machine Policy can be used to make sure that all users who log on to the computer publish a uniform Free/Busy amount at consistent intervals. The Office Resource Kit for the required version of Microsoft Office contains the Outlook administrative template (.adm) file. Use this template to deploy the Group Policy or Local Machine Policy settings for Outlook.

The Free/Busy settings are stored as part of a user's profile in the following registry key, listed by Microsoft Windows version:

Windows XP

HKEY_CURRENT_USER
 \Software
  \Microsoft
   \Windows NT
    \CurrentVersion
     \Windows Messaging Subsystem

To specify the number of months to publish Free/Busy information, change the following registry value to a value between 0 and 12: 
 
   Value Name: 00030330
   Value Type: REG_BINARY
   Value Range: 00 00 00 00 (0) to 0c 00 00 00 (12)
To specify the update interval to publish Free/Busy information, change the following Registry value to a value between 60 and 5940 seconds: 
   Value Name: 00030331
   Value Type: REG_BINARY
   Value Range: 3c 00 00 00 (60)  to  34 17 00 00 (5940)
For example, to specify an update interval of 60 minutes:
60 min. * 60 secs. = 3600 (decimal) = E10 (hex) = 10 0e 00 00
