I recently set up the automated purchase order approvals in Navision. I have created the hierarchy of purchasers and approvers in the document approval section of Navision. I have also set up the automated emails from Navision to Outlook. Unfortunately, I keep getting this message when I try to send my purchase order for approval. The system will not let me send my PO for approval nor will it let me send an email through Navision.

Please advise,

Thanks,

Pete

please check firewall settings and the smtp mail server entry.

also it's possible that the smtp server does not allow anonymous emails. in that case connecting to the smtp mail server needs valid credentials. check if you can setup the smtp server with credentials (user,pw).

Hi pete,

It seems that SMTP settings are not correct. Before checking it for approval emails, test the smtp by sending a simple Email.

Its seems you are using NAV 2009 then Try this to confirm that your smtp settings are correct or not -
