I have an Outlook file labeled outlook.msnpst which I believe is the old name for "'ost" files. It is orphaned and I cannot access the data. I have recreated the email account but Outlook always creates a new .ost file. Even if I swap names it says server is not avialable and I cannot open data. I noticed a post that said you could convert an ost file to pst but I did not understad how to use the command. Can anyone help in how to access the data on this orphaned file?
