Mail crashes when opening
I have an iMac 20-inch early 2008 running OS 10.11.6. Mail crashes when opening even when I open it pressing the SHIFT key.
I tested opening it using my guest account and it crashes there too. It is weird because I have the same mail accounts on my Macbook Pro running OS 13.6.3 and Mail works just fine there.
I thought of deleting the mail accounts from my Mail on my iMac but I don't know how to do it without opening Mail.
Any help will be most welcome.
