It is simple to combine several Outlook PST files into a single PST file using the latest technology. I recommend using the SameTools Merge PST program. This program allows you to quickly and easily combine all of your Outlook PST files into a single file that you can access from anywhere on your computer. Also, using this program doesn’t require any prior tech knowledge. This tool supports both ANSI and UNICODE formats for combining processes. All your data, including contacts, calendars, tasks, events, attachments, and other data, remains intact when you merge two or more Outlook PST files into a single Outlook PST file. You can use the program with any version of Windows. You can download the demo version of this program for free.
