11. Can Its works if I change the .eml extension with .msg?

Changing the file extension from ".eml" to ".msg" doesn't automatically convert the file format or content. While both ".eml" and ".msg" are email file formats, they are used by different email clients and have different structures.
Outlook generally supports the ".msg" format natively, and changing the extension might not directly convert the file to a valid ".msg" file that Outlook can read. ".msg" files contain specific metadata and formatting that might not be present in an ".eml" file.
To properly convert an ".eml" file to a format compatible with Outlook (.msg), you'll need to use a conversion tool or method designed to convert between these formats. Simply renaming the file extension won't suffice for proper conversion or compatibility with Outlook.
