I just noticed this yesterday. I went to add a user and it asked me if i wanted to create an exchange email address. I said yes but when i click on the properties of of that user and selected email addresses nothing was there. Usually it lists the SMTP address, CC MAIL, X.400, etc. Now it is blank and i have to manually add the email addresses i want. Any idea why? In the recipeint policy it does list those addresses and they do have a check mark next to them.
