Duplicate Data File Showing Twice In Outlook 2010, Same PST Opened Twice In Outlook
Earlier today I was troubleshooting a problem with sent items being displayed twice in my Outlook 2010 mail client. My configuration is definitely not standard and I have had issues before with some accounts putting two sent items in the same folder and some not however today all of the email being sent was showing up in my sent items folder twice. Initially I figured it would be a corrupt Outlook Rule or something similar but when I took at the list of my accounts in the left navigation bar within Outlook I noticed that one of my IMAP accounts was opened twice. I attempted to close one of the instances of the IMAP account without any luck. After messing around for a bit I was able to come up with a solution which is detailed below.
