When you are trying to create a PST file or open an existing PST file in a different Outlook install, you get the following message.
“Cannot move the items. You don’t have appropriate permission to perform this operation.”
Please locate the PST file and check if you have full control permission under security tab.
And please locate the following registry key:
HKCU\Software\Microsoft\Office\14.0\Outlook\pst
Dword: pstdisablegrow
Value: 1
Resolution
If the value is 1, pleaes change it to 0 and data could then be added to the PST file.
If you cannot find the key under the path above search HKCU for the word pstdisablegrow and change the value to 0
This will allow you to archive your information.
