However, before going any further and explaining how to do this, I must warn you that the content of the message will be 'searched' within the file to be opened.
If you urgently need to read the content of an email contained in an MSG file, you can take advantage of the program WordPad, which is already included in Windows. You can make a click law on it click the item To open with resident in the proposed context menu and choose the program from the proposed list Microsoft Outlook. Outlook is already installed on your PC, but you are on Windows and simply cannot open the MSG file of your interest with the method described above. If instead you wanted to use Outlook simply as viewer from MSG files and not as a mail client, put a check mark next to the entry Use Outlook without an email account on the first setup screen and press the buttons siguiente y to accept to confirm everything. If this is the first time you have started the program, the wizard will ask you to set up an email account: if you intend to continue, select the appropriate item and enter the required information in the proposed fields, then follow the instructions on the screen.
So if you have this software (included in the Microsoft Office suite), all you have to do is double-click the MSG file you want to view to open it with that program.
