Solutions to resolve ‘Cannot read from the source file or disk’

Solution 1: Make sure Outlook is closed

If you have your Outlook open, you may not be able to copy or move the PST file since it may be being accessed by Outlook. To avoid this problem, first close Outlook and then try moving the PST file. Ideally, this should help you resolve the problem. However, if this doesn’t help, proceed to the next step.
