Unable to use SMTP

[Duffman]

Hi @Svangeel89

Welcome to the Passbolt Community Forum!

Have you tried setting up an o365 app password

Cannot send email from passbolt docker to microsift office 356 outlook (smtp.office365.com:587))

Does the account you are using to connect to o365 have MFA set up on it? If so you’ll need an app password to use here

Also this link might help

Configure email providers

If that is not your issue can you please post your health-check
