|Message:||Process %1 (PID=%2). Active Directory contains invalid value for PollInterval attribute of OAB Virtual Directory object. The valid value range is 0-71582. The upper range limit value is used instead.|
This Error event indicates that the msExchPollInterval attribute of the offline address book virtual directory object contains an invalid value. The valid value range is specified in the event description. The Microsoft File Distribution service distributes offline address books and custom Unified Messaging prompts on an interval specified by the msExchPollInterval attribute.
Note The default value for msExchPollInterval is 480 (eight hours).
To resolve this Error, follow these steps:
Caution If you incorrectly modify the attributes of Active Directory directory service objects when you use Active Directory Service Interfaces (ADSI) Edit, the LDP (ldp.exe) tool, or another Lightweight Directory Access Protocol (LDAP) version 3 client, you may cause serious problems. These problems may require that you reinstall Microsoft Windows Server 2003, Exchange Server 2007, or both. Modify Active Directory object attributes at your own risk.
If you are not already doing so, consider running the tools that Microsoft Exchange offers to help administrators analyze and troubleshoot their Exchange environment. These tools can help you make sure that your configuration is in line with Microsoft best practices. They can also help you identify and resolve performance issues, improve mail flow, and better manage disaster recovery scenarios. Go to the Toolbox node of the Exchange Management Console to run these tools now. For more information about these tools, see Toolbox in the Exchange Server 2007 Help.
