I like to put all the pst files in a location other than its default - for instance - client machines have two HDD - I put the pst file & most other data files on the 2nd HDD so that if primary goes out data is ensured.  

Not realizing the affect - I attempted to colocate the ost file to the 'Outlook' folder where the client's real-time pst and archive pst files reside - I copied from one location to another - I did not move the originals.  I then added the OST file the Outlook data file location...  

This is the error client gets when activating Outlook: "File access is denied.  You do not have the permission required to access the file c:\users\username.domainname\AppData\Local\Microsoft\outlook.ost.  Immediately Outlook shuts down.

After searching for methods to change the Outlook\Options\datafile entry with the ost file - and realizing I didn't know where to look for an option excluding launching Outlook - I uninstalled Office 07 and reinstalled.  Launched Outlook - same error message. Same result.

Do I have to delete the client mailbox from within Exchange and rebuild the account?  What did I actually do (what damage did I cause) and how in the world do I fix it?

If you rename the file.old outlook should just download the data (ost is just a cache of the mailbox) again.
If that does not work open control panel and select mail.
delete the profile and create a new one linking in pst files the user had and everything will be as was.
