The Outlook error access denied is appearing because he has restored his PST file from a backup. The upcoming segment is based on how we solve Outlook access denied error.
If you have restored a backup of PST file from CD-DVD, you should always first copy it into your Hard drive and remove the read only attributes of the PST file from properties. Just right click on PST file and ensure that the “Read Only” option is not checked. If it’s checked just remove it and click on “Apply” button.
Apply same process even if you have backed up on external HDD, check out for attributes. My client has backed up his PST file via one of the online backup service so it gets restored on the hard drive and thus the read only attributes are not selected. We have also cross checked it using command line, and found that the file attribute was set to archive.
To open the restored PST file never use “Import function” in Outlook. Using this option may lead to PST corruption. So the best method to open PST file is:
Open MS Outlook >> click on file >> Open >> Outlook Data File and browse for the restored PST file >> select it and click Ok. Generally when this method is adopted the PST files and its content get opened. But we have other issue we are still getting outlook error “Access Denied”, it was pointing towards a file permission issue. So we made sure that the user was logged in as the Administrator.
