Sometimes your OST file becomes orphaned or corrupted and Outlook can’t open it. The
MSOutlookHelp OST to PST Converter lets you easily
convert OST to PST so you can open it again in Outlook or other email clients. It also lets you preview the contents before conversion, so you can decide exactly what you want to export. In addition, it handles encrypted or password-protected OST files without errors. Additionally, it can convert/import OST files to multiple email clients or into file formats.
