O365 Question

Hi, the E-mail configuration page is no longer blank after I re-deployed the appliance. Now I have an issue that the test e-mail fails. I have set it up in a way that O365 supports: https://docs.microsoft.com/en-us/exchange/mail-flow-best-practices/how-to-set-up-a-multifunction-device-or-application-to-send-email-using-microsoft-365-or-office-365

I have configured for direct send option and it failed. I have also created a mailbox (licensed) in O365 in order to use the normal SMTP flow (not direct send) – this config and result of test mail you can see below. Please, advise.

Please fill outÆ
