SYMPTOMS

When you view the properties of an attachment in Microsoft Outlook 97, the size of the attachment may appear to be smaller than its actual size. The size displayed in the Properties dialog box is rounded down to the nearest kilobyte (KB), megabyte (MB), or gigabyte (GB). The following examples illustrate this behavior:

   Actual Size       Display Size     Difference
   ===========       ============     ==========

     1.0 KB              1KB             -
     1.4 KB              1KB          400 bytes
     1.9 KB              1KB          900 bytes

     2.0 MB              2MB             -
     2.2 MB              2MB          200 KB
     2.9 MB              2MB          900 KB

     3.0 GB              3GB             -
     3.3 GB              3GB          300 MB
     3.9 GB              3GB          900 MB

WORKAROUND

Open the message.
From the File menu, select Save Attachments.
Select the attachment from the list, and click OK.
Save the file to a directory on your hard disk drive.
