SMTP relay crashes on startup

[Simcfc73]

Hi,

 

I made a massive booboo by updating a server to server 2020 which had a smtp relay on it.... which doesn't start up now and crashes.

 

I decided to replicate it on an old server but I'm getting AUTH errors each time I try and send emails.

 

I've got a connector on the O365 domain.. set the correct settings in IIS SMTP and have a cert on the TLS page.

 

Bit confused

Smtp relay has been deprecated since Server 2012 and is planned to be completely removed from Server 2022 soon
