The Microsoft® Exchange Server Analyzer Tool queries the Win32_Directory Microsoft Windows® Management Instrumentation (WMI) class to determine the value of the FSName key for the Exchange SMTP PickUp directory. If the Exchange Server Analyzer determines that the value for the FSName key does not equal NTFS, a warning is displayed.
Microsoft does not support the storage of Exchange data files on non-NTFS volumes. Exchange data files include the following files:
- .edb files
- .stm files
- .log files
- .dat files
- .eml files
If you see this warning, you must move the SMTP PickUp directory to a folder on an NTFS file system drive. Alternatively, if the drive on which the PickUp directory is stored is formatted as a FAT drive, you can use the convert.exe command-line tool to convert the drive to NTFS.
For more information about moving the PickUp folder, see the Microsoft Knowledge Base article 822933, "How to change the Exchange 2003 SMTP Mailroot folder location" (http://go.microsoft.com/fwlink/?LinkId=3052&kbid=822933).
Alternatively, if the drive on which the files are stored is formatted as a FAT drive, you can use the convert.exe command-line tool to convert the drive to NTFS. For information about using the convert.exe command-line tool to convert a FAT partition to an NTFS partition, see the Knowledge Base article 214579, "How to Use Convert.exe to Convert a Partition to the NTFS File System" (http://go.microsoft.com/fwlink/?LinkId=3052&kbid=214579).
