A BlackBerry user at our organization has been using a generic inbox (e.g. email@example.com) as a contractor. Now they are full-time, and have a new, personal AD account and Exchange mailbox (firstname.lastname@example.org). We are not migrating or deactivating the generic account: this is a new, separate inbox.
On BlackBerry Enterprise Server Express 5 connected to an Exchange 2010 server, how would I update the existing BlackBerry ID associated with email@example.com to sync with the firstname.lastname@example.org inbox instead? This user does not want to lose his BlackBerry settings (other than the generic account's calendar, contacts, etc.) and downloaded apps by performing a security wipe and creating a new BlackBerry ID.
