The employee who set up Thunderbird for us, has moved on to a different line of work & no longer with us. Her name is on all the emails and templates. How do I change these and how do I secure our emails from her use now that she moved on? I edited & saved each and every Template earlier today. Then, when I went to check my work, nothing had changed. Help me please.....and talk to me like I'm just beginning computers, because...I am.
