SYMPTOMS
If you delete data from an Outlook 2000 personal folders (.pst) file, AutoCompact only compacts a small amount of the file.



CAUSE
When idle, Microsoft Outlook begins the .pst file AutoCompact process. This process only runs for approximately 30 minutes before the .pst file is automatically disconnected. This process ensures that the file is not locked indefinitely after Outlook has been left open, and permits any backup programs to back up the .pst file. Because of this process, only a small amount of the .pst file compacts.



RESOLUTION
To resolve this problem, obtain the latest service pack for Microsoft Office 2000. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

MORE INFORMATION
For AutoCompact to compact a larger amount of data, Outlook 2000 must leave the connection to the .pst file open for a longer period of time after it becomes idle. After you install this hotfix, follow these steps to change the registry to control the duration of the connection to the .pst file.

How to Increase the Duration of the .pst File Connection During the AutoCompact Process
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

 Click Start, and then click Run. In the Open box, type regedit.exe, and then click OK. Locate and then click the following key in the registry:

HKEY_CURRENT_USER\Software\Microsoft\Office\9.0\Outlook

</li> On the Edit menu, click New, and then click Key to add a key with the following name:

PST

</li> On the Edit menu, click Add Value, and then add the following registry value in the new PST key:

Value name: PSTDisconnectDisable

Data type: DWORD

Value data: 0

</li> On the Edit menu, click Add Value, and then add the following registry value in the new PST key:

Value name: PSTDisconnectOverrideCompact

Data type: DWORD

Value data: 14400

</li> Close Registry Editor.</li></ol>

NOTE: The PSTDisconnectOverrideCompact value is specified in milliseconds. The previous example uses &quot;14400,&quot; which equals 4 hours. If you do not have to unlock the .pst file, you can set the PSTDisconnectDisable value to 1 to keep the .pst file open indefinitely.
