Aid4Mail version 5 can reliably and accurately convert OST files to PST files. If you have an Aid4Mail version 4 license, please get in touch with us for licensing options.
Compared to competing products, Aid4Mail is faster, more accurate and offers more control over the conversion from OST to PST. It can handle very large OST files and even recover mail from corrupt OST files.
Fookes Software has been developing Aid4Mail for over 20 years and we offer a free trial so you can test it out yourself.
