Message Text

Process %1 (PID=%2). Could not find directory %3. This is normal if it has never been generated. Otherwise, make sure this directory and share has read permission for "Exchange Servers" group.

Explanation

This event indicates that Microsoft Exchange File Distribution service did not find an offline address book (OAB) file. If this event is logged, the ExchangeOAB directory could not be found on the 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) connects to the ExchangeOAB directory for offline address book (OAB) files so that these files can be distributed to 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.

User Action

To resolve this warning, do the following:

  • Open the directory in which Exchange has been installed on the Exchange server that logged this event. For example, open C:\Program Files\Microsoft\Exchange Server. Then, verify that the ExchangeOAB directory exists. If it does not exist, run the following Exchange Management Shell command:

    Update-OfflineAddressBook "Default Offline Address List"

    If the ExchangeOAB directory exists, make sure that it is shared and that the Exchange Servers group has the Read permission assigned. For more information, see Update the Offline Address Book.

For More Information

If you are not already doing so, consider running the Exchange tools, which have been created to help you analyze and troubleshoot your Exchange environment. These tools can help make sure that your configuration aligns with Microsoft best practices. They can also help you identify and resolve performance issues and improve mail flow. To run these tools, go to the Toolbox node of the Exchange Management Console. To learn more about these tools, see Managing Tools in the Toolbox.
