If you are in need to recover data from corrupt OST file, then manually it isn't possible. The reason behind this is that if you have orphaned OST file then it's for sure that without it's known Outlook profile, you can't access it or repair corrupt OST file. It becomes corrupt or inaccessible which may hinder your access to important emails and data.
Therefore, it is suggested to choose an authentic way to repair corrupt OST files. I have a better approach for it that really worked for me also. Advik OST Repair Tool is one such application that efficiently and effectively recover corrupt data from OST file.
