did you receive my answer?
Josh, message reads
Cannot start MS Outlook. Cannot open Outlook window. The set of folders cannot be opened. The outlook data file C:\Users\QWERTY\AppData\Local\Microsoft\Outlook.pst was not clearly closed by the last programme that used it. It cannot be opened until repaired
Windows 7 running office 2013
Try both the Quick Repair and Online repair then open Outlook again. Let me know if the error message is still there.
