Having trouble trying to delete 42GB of 'Mail' App Data

Hello there, Greetings from Seoul. I'm having a wee bit of trouble trying to figure out a way of deleting the 'Mail' app data which, according to the 'Storage' section of 'About My Mac', is taking up 42GB of space on my hard drive. I've deleted the account that was previously linked to the 'Mail' app so every time I open the app now it prompts me to setup a new account. I'd very much appreciate any direction you could offer. Very Best and have a nice Sunday, Martin

If you want to nuke ALL old Mail.app data (i.e. not just that deleted account), try to delete these folders (but do make a backup of your system first or at least compress those folders as .zip and put them in some other folder!):

~/Library/Mail

~/Library/Containers/com.apple.mail

And maybe also:

~/Library/Accounts

Then log out/in before opening Mail. Or Shift-boot into SafeMode while doing all that.

Many thanks, Matti. I’ll save my work on an external hard drive in the morning and let you know how I get on! Thanks again :-)
