      Thank you for buying Remo Repair Outlook PST. Sincere apologies for the delayed response. I noticed that you have only used normal scan option to fix your inaccessible PST file. Normal scan ensures quick PST repair and comes in handy when the PST corruption is minor.

      Select Open Default PST file and click Next > Select Smart Scan option and Destination path to save your repaired PST files > Now, click Repair option.
