I had a lot of PST files and wanted to merge them but I didn't know of any good tool. Then my friend informed me about MailsDaddy PST Merge and Join Tool. With the help of this tool, I was able to merge all the PST files. This tool supports all MS Outlook versions 2019, 2016, 2013, 2012, 2010, etc.
