The free utility converts messages, contacts, appointments and meetings, tasks, notes, and other Outlook items from MSG files to PST. From a large number of MSG files in different folders, depending on the settings, you get one or more PST files. This creates the Outlook folder structure of the correct type. You can immediately split the resulting PST files by size, year, or other parameters. Outlook can use PST and MSG files to store its data, with the difference that the MSG file contains one Outlook item (message, contact, task, etc.) only, and the PST file contains folders of different types that store many Outlook items. After conversion, the resulting PST files can be connected to Outlook using built-in functionality. If you specify an additional destination folder name, a folder with that name will be created in the resulting PST file, and all the converted data will be placed in it. In the name of this folder, you can use the same macros as in file names. Therefore, additional sorting of items by dates, parts of subject, addresses, and other message fields is supported. To get PST files in the same folder structure as in the source folder on the disk or network share, simply leave the name of the additional folder empty. By configuring filters, you can convert only contacts, only messages with attachments, only files smaller than the specified size, and many other options. All images, HTML formatting, attachments, and properties from MSG files will be retained in their original form. During the conversion process, you can move the source MSG files to another folder. This allows you to run the conversion several times with no duplicates appearing in PST files. You can convert MSG to PST in batch or automatic mode using the command line. The command line utility allows you to convert MSG files to PST on a schedule, use the utility in various migration scenarios, and backup Outlook data.
