Hello folks,
I know that there have already been other threads regarding SMTP issues with Office365 servers but unfortunately nothing worked for me.
I double-checked the credentials and the official Office365 SMTP settings. But no matter what I do, I always get a "Login denied.
501" whenever Zabbix tries to send any E-Mail. I know that the Office365 is working as I use it in other e-mail notification services as well and those work without any issues.
Here's my configuration:

I'm running the Zabbix 3.4 appliance which runs Zabbix server 3.4.7.
I'd appreciate any kind of help. Maybe I can setup a local postfix server to relay the messages? Is that possible?
