Essential Exchange

In August of 2010, I posted Generating a report on Distribution Groups and their Membership . For most people, that script worked just fine.

Long ago and far away (way back in 2006) I wrote an article for finding the disk space used by Exchange 2000 and Exchange 2003, Finding disk space used by Exchange .
