It allows you to apply selective approach for conversion rather than converting the entire OST. You can choose specific email messages from the OST, based on various parameters such as 'To', 'From', 'Subject', and 'Date' and convert each of them into a variety of formats including MSG, EML, RTF, HTML, and PDF formats. You can also convert the chosen emails to a single PST file. This feature makes the tool highly flexible.
You can split the ‘scan and preview’ process and the ‘saving’ process. Save the scanned and converted data in the DAT file format by clicking ‘Save Scan Info’ button. Resume the operation later or save the converted OST again by loading this DAT file. The method is useful when the user is unable to carry out the entire OST to PST conversion process at one-go or wants to keep the scanned information to use it whenever required without wasting time in repetitive scanning.
It maintains the Outlook-like structure and allows you to sort and organize your email messages by Date, From, To, Subject, Type, Attachment, Importance, etc. before saving the converted OST. Additionally, it lets you improve scan result readability by allowing you to segregate emails in groups by using a convenient “Show in Groups” feature.
