Reports Not Sending Via Email

Hi,

I've setup a Destination Email in the AdaptiveJobServer as per this article

Configure SMTP server in SAP BO and Schedule webi Reports for Email as Destination

I've tried different all the different authentication methods but every time I run a report it fails with this message:

I can telnet to the Mail Server (Exchange 2010) so I'm pretty lost.

Any advice would be great.

Thanks 😊

Darren
