"Invalid e-mail alias" in SBS 2008 console

In SBS 2008 using Exchange 2007, when in the SBS console, I changed someones redirected folder quota.  When I clicked OK, it went back to the General category, and pointed to the E-mail Address field and said: "Invalid e-mail alias.  This e-mail alias already exists.  Type a different e-mail alias"

What gives?  This account has been set up for ages.  The only way I could get out was to change the address there to something else.  Now I can't get back to the original email address.

I've googled this, and though there are many who mention this problem, I've never seen a single solution.

My Exchange 2007 version is 8.1 Build 240.6

Is there another user or possibly a public folder or maybe even a distribution group that has this alias? Or does the original one have a space in?

To eliminate the SBS console as being the problem, can you change it back using the Exchange Management Console?

Both the old address and the new one that I "had" to create are there in EMC.  The new one is her main one (bolde).  "Set as reply" is greyed out for both addresses.  If I create another email address in there, I cannot set that one as the reply one either.
