I have hundreds of .eml files that I want to convert to .mbx files. I can save each one as a text file & delete the HTML, but I don't want to do that. I tried an experiment. I changed the extension on one of them to .html & opened it in Firefox. I could still see the HTML. Most, if not all, of the .eml converters are Windows-based. One option is to download a 30-day trial version of Office 365 for Mac. Since I have a mini & a laptop, I probably could get a total of 60 days to convert all of my .eml files to .mbx files. I don't know what the export options are for Office 365. I don't even know if .mbx is an output option for Office 365. Of course, there's only 1 way to find out! I wondered about importing my .eml files into my gmail account, but that isn't possible. I read on the 'net that if one double-clicks on a an .eml file, Mail will open. It opens alright, but I have to create an account. I can create a Yahoo account, but then Mail will download my e-mails from my Yahoo account. I have a netbook with Windows XP on it, but I'm sure that .mbx isn't an output option from Outlook Express. I haven't seen any free Mac-based .eml to .mbx converters. What do you guys use to convert .eml files to .mbx files?
