    It is a great pity that you do not provide support here. We would even be willing to pay for a working solution.

    @miksbl Did you find a solution? Almost one month later and no response?

    I am guessing another plugin is required – did you find anything that works with O365

    Still no answer and no solution…..

    I need still an answer. Also other users have the same issue (see comment from user SJW): https://wordpress.org/support/topic/php-fatal-error-uncaught-error-class-name-must-be-a-valid-object-or-a-string/
