Outlook 2010 you don’t have appropriate permission to perform this operation.
I have a user who when they go to File > Open > Open Outlook data file they get an error "you dont have appropriate permission to perform this operation. " I've completed the following troubleshooting steps: 1) Repaired Office, 2) Created a new Windows Profile, 3) Created a new Outlook Profile, 4) Elevated user rights to an admin, 4) Re-installed Office 2010 5) Confirmed there is no GPO or registry setting preventing me from selecting this option. This is on a Windows XP SP3 machine with Office 2010.

Make sure that Outlook is fully patched

Verify that the data file exists and you have enough permissions at folder level or you're doing this at UAC enabled. So you need to ensure Read only attribute is not applied on the .PST file
a.  Right click on the File > Properties > Attributes > uncheck Read-only option
b.  Apply the settings
c. If the issue still persists, remove Outlook.dat and Outlook.srs file from the following location:

 C:\Users\<username>\AppData\Roaming\microsoft\Outlook

Let me know how it goes.

I'm running in to the same issue, and it affects me on both 2010 and 2013.  It's not a permission error with a particular PST file, as I can't even get to the point where I'm selecting a file.  I get the 'You don't have appropriate permission to perform this operation" error as soon as I click on the Open an Outlook Data File button, not when I select a particular PST.

Wiping the user profile / mail profile does not fix the issue.

Were you ever able to resolve it?

I have the same problem as CTDHelpdesk and have been unable to find an answer anywhere.  Immediately after choosing "Open Outlook Data File" Outlook 2013 (Win7) moves to the Outlook Today view and issues the popup "You don't have appropriate permission to perform this operation".  NB this is before any file selection dialog appears, so it could not relate to any particular data file or location, as none has been selected.  

I have previously opened these data files in this version of Outlook 2013, and I can't think of anything that might have changed.  In fact, inconveniently, while trying to fix this problem I closed two open PST files that I use frequently and now can't reopen them because of this error. 

I've tried step (c) above.  (a) and (b) don't apply because I can't even select a PST file. I've also tried "Run as Administrator".

Ok I found out how to fix my version of the problem, based on technet post af552a8d-51bd-4b32-9590-f4d51e3c5224.  (Sorry, I don't have user permission to post a link here.  Irony.) 

I changed the key value "HKEY_CURRENT_USER > Software > Microsoft > Windows > CurrentVersion > Explorer > User Shell Folders > Personal" to my C drive and the problem went away.

This link sorted the update issue for me immediately but do not reboot until both uninstalled and follow exactly

waiting verification of my details so  cannot paste links today guys http www  inmotionhosting (dot) com support/news general/imap-issues outlook-2013

I actually got here by typing in Google IMAP issues

to clarify go to Inmotionhosting (dot) com and search for Outlook 2013

Forgot to say > disable auto download as it will keep trying to reinstall patch's, then hide when it comes up again in update..

I have had this problem for several months and all the answers here and other places on the web did not work. (Of course, the obvious first thing to do is make sure the file is not read-only and that I have permisisions to modify it - I had full (admin) perms.)

I finally worked out how to fix it: Search the registry for all occurrences of the key "PSTDisableGrow" and change the values to zero.

This was my issue also.  My personal drive was missing and this key pointed to a path that didn't exist.  

Thanks for the tip.

I am using Outlook 2010 and I was able to add the PST (Open Data File) without any problem. But, I used to get this error any time I try to move mails to the PST from the Exchange Mailbox.

APhillips's solution worked for me. Thanks a ton!!!

I finally worked out how to fix it: Search the registry for all occurrences of the key "PSTDisableGrow" and change the values to zero.

This is where the key was located on my Registry: HKEY_CURRENT_USER > Software > Policies > Microsoft > office > 14.0 > outlook > pst
