I have a customer using Office 365 and Outlook 2013. Customer's Outlook was configured with a generic email address receptionist@companyname.com. Eventually we changed the primary exchange email address to employeename@companyname.com and made receptionist@companyname.com an alias. The issue we are having is the Outlook name in the left menu tree still shows receptionist@companyname.com. The end users wishes to see the correct email address. I know we can recreate the Outlook profile but was wondering if there is a way to just rename it.
