Having worked with Outlook for quite a long time now, I have my data stored in multiple PST files. To make the data accessible from a single file, i wanted to merge all the files together. Thankfully, INTRIGUA Merge PST software helped me in doing the same without data loss.

I have data stored in multiple PST files that contains duplicate items. The INTRIGUA Merge PST tool not only helped in combining all the PST files in a single file, but also helps in removing duplicate items from the files before merging. Thanks team for the great work.
