The Microsoft® Exchange Server Analyzer Tool queries the Active Directory® directory service to determine the value for the msExchEDBFile attribute of each public folder store object. This attribute specifies the location of the database files used by this public folder store.
The Exchange Server Analyzer also queries Active Directory to determine the count of the values listed in the homeMDBBL attribute of each mailbox store on this server. The count of this attribute represents the number of mailboxes on the mailbox store. The Exchange Server Analyzer can then calculate the total number of mailboxes managed by the server.
If the Exchange Server Analyzer finds that the msExchEDBFile attribute starts with \\ on an Exchange Server with more than 50 mailboxes, an error is displayed.
This error indicates that the database files for the public folder store are being stored on a network share. If the msExchEDBFile attribute starts with \\, it indicates that the log file path uses a Universal Naming Convention (UNC) path. This is not a recommended practice as interruptions in network connectivity could cause database errors, resulting in lost data or corrupted databases. It is recommended that you correct this problem as soon as possible.
To move the database files to a new drive
In Exchange System Manager, expand the Exchange server object on which the store resides, expand the appropriate storage group container, right-click the public folder store object that you want, and then click Properties.
Specify new file locations on the Database tab of the Properties dialog box.
