My mail icon has a black dot underneath showing it is in use. l am unable to open the mail to view messages. I am unable to close the mail application. When I try to shut down, I get a message that I cannot shut down because my mail is open.
I am unable to open my mail or close down my computer because I get a message that my mail is open. How can I view my messages when the folder won't open and I can't shut down my computer?
