I've been reading a lot of things on the internet about this but can't get it to work. Also tried the Mozilla forums, did not get anything useful out of that.
What I could do is importing the PST files, but the plugin for that is outdated.. Which makes it a bit of a problem. I would also like to migrate all my account settings with this as well, I have 8 accounts running in outlook.
Does anyone know a simple way of doing this? And no, tools -> import doesn't work. Gives me errors, tried all of them.
