I recently tried an automated solution named Shoviv MSG converter to convert some of my MSG files into PST format. The tool is quite convenient and has everything a user needs. With this converter tool, you can also upload MSG files into Live Exchange and Office 365 mailboxes. It also provides a filter option on the Subject, To, and From-based criteria. I suggest you use this MSG file converter tool to upload your files into Office 365, Live Exchange, and Outlook PST format.
You can evaluate the software skills by using the trial version. It allows the processing of the first 50 items per folder with all paid features.
