Today I made a script as requested by Jamal.
It is a further development of a script to enumerate all exchange mailboxes and their size which can be found here.

What the script does:

• ask for the smtp address of the mailbox
• get the displayname and homembd properties of that mailbox
• enumerate all exchange servers
• make a wmi connection with the exchange server on which the mailbox resides
• get the size of the mailbox

The script is tested in an win2003/exchange2003 environment.

Follow the next steps to run the script (admin rights needed):

• copy and paste the script in your favorite text editor
• save the script (for example c:\temp\mailboxsize.vbs)
• open a command prompt
• go to “c:\temp”
• give “cscript mailboxsize.vbs” (without quotes) and enter

The script:

Happy scripting.
