XADM: Temp Files Remain After OAB Generation Fails

Generating an Offline Address Book (OAB) on a drive that has low disk space will fail, leaving the drive with temp files related to this unsuccessful operation.

When you generate the OAB within the Microsoft Exchange Administrator program, temporary files are created. Running this task on Microsoft Windows NT Server causes these files to be created on the system drive of the server or in the location to which the Administrator points the %temp% and %tmp% environment variables.

If the directory service is large and low disk space conditions are encountered on the server, an error may occur and you may receive the following error message: The following information is written in the application log in the Windows NT Event Viewer:

The remaining temp files are not automatically deleted and must be deleted manually. If temp files still remain, repeat the operation to complete. It is commonly expected that temporary files associated with failed attempts would be deleted, but in this case, they are not.
