Symbolic Name

evtOALManifestNotFound

Message Text

OALGen failed to find the OAB version 4 manifest file '%1'. This is normal if it is the first time this offline address list has been published to the file system. Check other logged events to see if this is a serious error.

Explanation

Event error ID 9390 indicates that either this is the first time that the offline address book (OAB) was created or that the file was accidentally deleted.

User Action

To resolve error event 9390, determine if the OAB was created for the first time or if the OAB was accidentally deleted. If the OAB was accidentally deleted do one or more of the following:

  • If daily backups are available, restore the content of the OABGen folder to the <ExchangeInstallDir> \ExchangeOAB\ <OAB GUID> folder (where <ExchangeInstallDir> is a placeholder for the Exchange 2010 installation directory and <OAB GUID> is a placeholder for the name of the folder).

  • If the corrupted OAB item is enabled for public folder distribution and the data has been published to public folders before the OAB item was corrupted, you can delete the contents of the OABGen folder from the <ExchangeInstallDir> \ExchangeOAB\ <OAB GUID> folder and rebuild the OAB files by updating the OAB. For more information about how to update the OAB, see Update the Offline Address Book.

  • If neither daily backups nor public folder distribution is enabled, delete the contents of the OABGen folder from <ExchangeInstallDir> \ExchangeOAB\ <OAB GUID>, and then rebuild the OAB files by running the following command in the Exchange Management Shell:

    Update-OfflineAddressBook <OABGuid>

    Important

    This procedure causes a full OAB download by all clients. A full OAB download can cause considerable network traffic between Client Access servers and clients.
