|Message:||Process %1 (PID=%2). Could not find directory %3. This is normal if the directory has never been generated. Otherwise, make sure this directory and share has read permission for the “Exchange Servers” group.|
This Warning event indicates that the ExchangeOAB directory could not be found on the server that is running Microsoft® Exchange Server. This is typical if Oabgen.dll (referred to as OABGen) has never been run on this server. The Microsoft Exchange File Distribution service (MSExchangeFDS) will connect to the ExchangeOAB directory for offline address book (OAB) files so that these files can be distributed to Microsoft Outlook® clients. If MSExchangeFDS cannot find the ExchangeOAB directory, OAB distribution to Outlook clients may not work. This event may also occur if MSExchangeFDS does not have the necessary permissions to access the ExchangeOAB directory.
To resolve this warning, follow these steps:
On the Exchange server that logged this event, open the directory where Exchange has been installed, for example, X:\Program Files\Microsoft\Exchange Server, and make sure that the ExchangeOAB directory exists. If it does not, run the following command from Exchange Management Shell:
Update-OfflineAddressBook “Default Offline Address List”
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.
