SYMPTOMS
An error message similar to the following may appear when you run the Exchange Server Performance Optimizer against a private-only server or public-only server:

The file D:\Exchsrvr\mdbdata\Priv.edb (or Pub.edb) could not be found. - [800FF330]

This error message may reference the full path to the Priv.edb or Pub.edb database. This error message appears while Performance Optimizer is running a disk analysis against the local drives.



CAUSE
This issue can occur because, when the disk analyzing portion of Performance Optimizer is running, Performance Optimizer always checks for the existence of the Priv.edb and Pub.edb databases, whether these files are being used or not. Performance Optimizer reads the Exchange Server registry keys to determine where these databases are supposed to be located. If the databases are not in the path that is specified in the registry, an error message is generated.

A private-only Exchange Server computer does not use the Pub.edb database, and a public-only Exchange Server computer does not use the Priv.edb database. For this reason, the Pub.edb or Priv.edb may have been manually deleted to free disk space on a private-only server or public-only server. When you delete the Private Information Store object or Public Information Store object from the Exchange Admin program, the corresponding database is not removed from the drive by Exchange Server. The database is left on the drive but the database is not used.



WORKAROUND
To work around this issue, use one of the three following methods:

Method 1
Create a sample database file in the path specified in the registry. For example, you can create a file with Notepad. Once the text document is created, you can then rename the file to Priv.edb and place it in the appropriate path. Performance Optimizer does not check for a valid database, but rather, it simply checks for the existence of files named Priv.edb and Pub.edb. The easiest way to determine where the newly created file should be copied is to click the Database Paths tab in the properties of the appropriate server object in the Exchange Administrator program. The list of servers in the site is maintained in the Site\Configuration\Servers container of the Exchange Admin program.

Method 2
Run Performance Optimizer in verbose mode by running the Perfwiz -v command from the Exchsrvr\bin directory at a command prompt. When you run Performance Optimizer in verbose mode, you are given the option to &quot;Analyze hard disks.&quot; If this option is unchecked, Performance Optimizer will not check for the existence of a Priv.edb or Pub.edb database file.

Method 3
If you are using Performance Optimizer solely to modify the database paths, do not use Performance Optimizer; move the database(s) by modifying the database paths in the Exchange Admin program.

MORE INFORMATION
A private-only server or public-only server is a server from which the private information store or public information store object has been deleted in the Exchange Admin program (for example, dedicated mailbox servers or dedicated public folder servers). A private-only server or public-only server can improve performance by allowing the Store.exe process to dedicate all processing time and allocated memory to one Information Store database rather than two databases (Priv.edb and Pub.edb).
