This is on SBS 2003. An employee got married, she asked me to change her email address from firstname.lastname@example.org to email@example.com.
I simply added the firstname.lastname@example.org as an additional email address to her user account, unchecked the checkbox on the Exchange Email Addresses tab of her user account that says something like "Update email addresses according to policy," and then set the email@example.com as the Default email address.
Had her send me some emails, I replied, and things looked good. This all happened about a week ago. then today I was onsite and she tells me that she hasn't received any external email since we changed her email address.
What am I missing? I'm about to simply create a new user account for her and if Exchange doesn't let me create a new user account with the email address of firstname.lastname@example.org because it now already exists in AD, I'll just use email@example.com I guess.
