Moving to MozillaZine Tech as this is really an Outlook question rather than a Thunderbird question.

Messages can be exported from Thunderbird to EML format en masse using the ImportExportTools extension --

Maybe try these sites for information on the import side of the equation -- ... tlook.html ... -files.htm

Aid4mail is pretty good a converting mail between different formats, but the trial version is limited to processing a maximum of 50 messages per mail folder.

If you want to move messages between Thundebrird and Outlook I suggest you think about using the same IMAP account for each. That minimizes the problems of converting message formats. You can import the .EML files into Thunderbird using the ImportExportTools add-on. Outlook supports exporting messages as .MSG files.
