We renamed a user via the SBS2011 console. It appeared to update everywhere. However when other domain users use Outlook to connect to the user's shared calendar it still has the old username.
Ex: rename User1 to User2. When User3 connects to User2's shared calendar it still shows User1's name in the calendars list.
Active directory has the correct info, and everything seems to be in place, our only issue is with the wrong name showing up in the shared Outlook calenders. Removing and recreating the account isn't really an option because of all the information tied to this specific user's account.
Why would this be happening?

Assuming that the user name appears correctly in the Global Address List and Offline Address Book, you may need to reset the Outlook Nickname cache, as described here:
How to reset the nickname and the automatic completion caches in Outlook

Microsoft Outlook maintains a nickname list that is used by both the automatic name checking feature and the automatic completion feature. The nickname list is generated automatically as you use Outlook. If the nickname cache is corrupted, Outlook may be unable to identify recipients, may offer incorrect recipients when automatically completing the email address, or may send the message to the wrong person.
Unlike earlier versions of Outlook that store the nickname cache in a file on your computer, Outlook 2010 stores the nickname cache in your primary message store. For example, if you are using a Microsoft Exchange Server account, your nickname cache is stored in a hidden message in your mailbox.
