This is a single Exchange server, in windows 2003 AD Domain. Recently, I tried to do a cleanup so as those unneeded accounts, mailboxes have to be deleted. <br />
<br />
I found that there are quite a number of mailboxes with its original users already deleted. When I tried to delete these mailboxes in the ESM, I was surprised to found that the &quot;purge&quot; function is greyed-out. <br />

How should I able to delete those mailboxes?
