Welcome to the EMD Forums!

First you might try:
Repair Outlook Data Files (.pst and .ost)

The OST file might be marked as read-only, and if so you probably want to uncheck that setting.

OST files are not really designed to be imported, but evidently there are work-arounds. See:

• Introduction to Outlook Data Files (.pst and .ost)
• Open or import items from an offline Outlook Data File (.ost)
• Opening an OST file in Microsoft Outlook
• I think there may be some OST to PST conversion programs.
