I want to migrate from Gmail to something else. Gmail cautions that once you leave Gmail you emails are deleted. Gmail has this app called Takeout for moving existing emails, address book, etc into a zip file for transferring. My question is: isn't this already being done by the Thunderbird profile folder. Can't I just install TB with my new email provider and everything from the past is there? I have heard people say that using Google Takeout did not work for them. Thanks,
