Outlook 2010 – You don’t have appropriate permission to perform this operation – Import PST

While attempting to import a PST you may receive the error: You don’t have appropriate permission to perform this operation

The most common cause of this is profile specific. Try creating a new mail profile using these instructions from Microsoft, and import it to the new profile instead.

Otherwise, check to see if Group Policy is disabling PST usage.
