Mail will not open. Keeps saying "No Mailbox selected". if i hit cancel, it closes.

Wants me to set up accounts. But, if I try it says: Duplicate account, and crashes.

This is an "all of the sudden" problem.

Have tried safe opening, restarting, etc.

Please open the Internet Accounts preference pane and see whether there is a duplicate account.
