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
