SYMPTOMS
When you use Microsoft Exchange Server 2003 Outlook Web Access to recover public folders, you cannot recover some large, nested public folders. Additionally, the information store becomes unavailable to users.



CAUSE
This issue occurs if the version store reaches its size limit during the recovery process.



WORKAROUND
To work around this issue, you can temporarily increase the size limit of the version store. The setting for the msExchESEParamMaxVerPages attribute for the storage group object in the Active Directory directory service determines the size limit of the version store. This setting is in units of 16 kilobytes (KB). By default, the msExchESEParamMaxVerPages attribute is set to 9,280 KB. To resolve this issue, you can increase the attribute to 20,000 KB. However, this setting leaves less available memory for other functions in the version store. Additionally, this setting may cause other performance issues.

To increase the size limit of the version store, follow these steps.

Warning If you use the ADSI Edit snap-in, the LDP utility, or any other LDAP version 3 client, and you incorrectly modify the attributes of Active Directory objects, you can cause serious problems. These problems may require you to reinstall Microsoft Windows 2000 Server, Microsoft Windows Server 2003, Microsoft Exchange 2000 Server, Microsoft Exchange Server 2003, or both Windows and Exchange. Microsoft cannot guarantee that problems that occur if you incorrectly modify Active Directory object attributes can be solved. Modify these attributes at your own risk.  Install the Microsoft Windows Server 2003 Support Tools. To do this, follow these steps:  Insert the Windows Server 2003 CD into the computer's CD drive. Click Start, click Run, and then click Browse. Locate the following folder on the CD:
