If you're looking to convert EML files to MSG, you can do it manually by opening the EML in Outlook and saving it as an MSG file—but that’s slow and tedious if you have multiple files.
A better option is DRS Softech EML File Converter, which lets you: Convert multiple EML files to MSG in bulk
Preserve original formatting, attachments, and metadata
Work with all Outlook versions (2003–2021 & Office 365)
Save time with a simple, user-friendly interface
Manual conversion works for one-off files, but for efficiency and reliability, a dedicated tool is the way to go.
