If you want to combine old and new PST files into a single mailbox, using the GainTools Merge PST Tool is a simple solution. Users can use this utility to combine several PST files into one without losing any emails, contacts, calendars, or attachments. To combine the old and new PST files into one PST mailbox, all you have to do is install the software, add the files, and choose the "merge" option. It also keeps the original folder structure and gets rid of any duplicate objects that can be there. It works well with Microsoft Outlook, so you can easily manage and retrieve all of your data in one tidy mailbox.
