I want to return my messages

I recently started with a very interesting problem, I sorted my box and could not open some messages that were themselves in the format of OST. experienced people advised me to convert these messages into the PST format. But this method also produced the following error OST file does not open and standard recovery tools open only a white blank screen.help me to restore all my messages there is a very important for me a picture and attachments to them.
