Are you dealing with duplicate MSG emails? I can suggest the easiest way to delete duplicate MSG files using the SameTools Remove MSG Duplicate tool. You can delete duplicate MSG files (messages, attachments, etc.) without losing any data using this tool. The application is also self-supporting and will not require MS Outlook to be on your computer. The tool works with each version of Windows (OS 10, 11, 8, 8.1, and 7). The best thing is you do not have to be need MS Outlook to use the software. It is very easy to use, and anyone can navigate the interface. Just a few clicks remove duplicate MSG files, upload your MSG mailbox files to the software panel, press scan, and the tool gets to work removing each duplicate MSG in your mailbox.
