I have some old encrypted OST files on my Windows computer and I am unable to read OST emails. All of my OST files are created with Microsoft Outlook and Exchange Server, now I want to reuse them in the easiest way. I noticed that HTML files can be open in any web browser by double-clicking which is a very nice feature for me. I want to change my OST files in HTML format so that I can easily read and share emails according to the requirement. If you have any solution then please suggest it to me.
