download sharedmailbox office 365 via IMPAP when user has 2-factor authentication enabled.

Hi all

Since Office365 enabled 2-factor authentication for my user, 
I am no longer able to download a shared mailbox connected to it via IMAP whit external application.

as username set: addressemaail@domain.com\sharedmailbox.
and my account password.

now the connection fails.
is there any way to solve?

Thank you
