I get this message when trying to log in to Thunderbird email program, "The current operation on "Inbox" did not succeed. The mail server for account luv2hke@yahoo.com responded [CLIENTBUG]. Help! Is Thunderbird still in business? Thanks, Claudia luv2hke@yahoo.com.

Chosen solution

Why install Thunderbird again? The Yahoo server issued the error message. Most have solved this by making sure your username in Server Settings is just the part before the @ sign.

If that does not fix it you could Google Client bug and see what it takes to fix Yahoo this time.

Does anyone know how to figure out what went wrong? Do I need to download the Thunderbird email program again?
