How to Change Account Order in Outlook 2010 and Later
If you use Outlook to access multiple email accounts, you may prefer to see them in a different order from the one Outlook uses to display them. If you use the Unified Inbox in recent Outlook versions, you can receive mail sorted by email account. Beginning with Office 2010, ordering how your email accounts show up in Outlook is only a matter of using your mouse to drag and drop accounts in the order you want them to display.
