Imcdump.exe is included with Exchange Server versions 4.0, 5.0, and 5.5. For
Exchange Server 5.5, Imcdump.exe is located in the root of the CD-ROM in the
Server\Support\Utils\<Platform> folder, where <Platform> is either

MORE INFORMATION
================

Imcdump.exe displays information about the internal representation of the
Internet Mail Service queues that is stored in the Queue.dat file of the Imcdata
folder.

How to Use Imcdump.exe
----------------------

Usage: imcdump <heap-path>
INBOUND|OUTBOUND|FREELIST|HEAP|<queuename>

The <heap-path> is the path to the Queue.dat file including the file name.
By default, the path is <Homedrive>\Exchsrvr\Imcdata\Queue.dat.

For example, to dump the INBOUND queue for the Queue.dat file that is located in
the default location, run the following command from a command prompt (start
from the same folder where the Imcdump.exe file is located):

  "imcdump <homedrive>\exchsrvr\imcdata\queue.dat inbound" (without the
  quotation marks)

When you run this command, the output is displayed in the window. To dump the
output to a file, run the following command:

  "imcdump <homedrive>\exchsrvr\imcdata\queue.dat
  inbound>c:\imcdump.txt" (without the quotation marks)
