2 years ago I had the same problem but with woocomerce, most emails were working, but some (password reset, new account) not.
What helped. If you are using SMTP settings with constants in wp-config.php, be sure that all your email constants, eg:
define( 'WPMS_ON', true );
define( 'WPMS_SMTP_USER', 'user@email.com' ); // SMTP authentication username, only used if WPMS_SMTP_AUTH is true.
define( 'WPMS_SMTP_PASS', 'somepassword' ); // SMTP authentication password, only used if WPMS_SMTP_AUTH is true.goes before that line:
/* That's all, stop editing! Happy publishing. */So it should be
define( 'WPMS_ON', true );
define( 'WPMS_SMTP_USER', 'user@email.com' ); // SMTP authentication username, only used if WPMS_SMTP_AUTH is true.
define( 'WPMS_SMTP_PASS', 'somepassword' ); // SMTP authentication password, only used if WPMS_SMTP_AUTH is true.
...
/* That's all, stop editing! Happy publishing. */And not:
/* That's all, stop editing! Happy publishing. */
...
define( 'WPMS_ON', true );
define( 'WPMS_SMTP_USER', 'user@email.com' ); // SMTP authentication username, only used if WPMS_SMTP_AUTH is true.
define( 'WPMS_SMTP_PASS', 'somepassword' ); // SMTP authentication password, only used if WPMS_SMTP_AUTH is true.See also https://wordpress.org/support/topic/smtp-error-could-not-authenticate-22/ And https://github.com/awesomemotive/WP-Mail-SMTP/issues/101
