Find Mailbox GUID's Exchange 2003

You may need to find the GUID's representing your Exchange 2003 mailbox databases. For example say you want to increase the database size limit to 75GB which is a registry change. This requires you to know the mailbox GUID's as shown in the image below:

An Exchange Engineer named "Bharat Suneja" wrote a really good visual basic script for achieving this which can be downloaded from here:

This script requires the Microsoft ArrayConvert libaries to be installed to function correctly. To download the ArrayConvert libaries visit Microsoft KB250344:

When downloaded extract the ArrayConvert files then copy and past all extracted files to the servers System32 directory:

Register the ADs.dll file using "regsvr32.exe ADs.dll" from the command prompt.

Navigate to the folder containing Bharat Suneja's script in command prompt and run the script using the cscript utility.
