SharePoint Stack Exchange is a question and answer site for SharePoint enthusiasts. It's 100% free, no registration required.

I have a list. When a user enables alert on this list then he/she is able to receive email from SharePoint when someone adds a new item or change item.

But emails sent by SharePoint workflow (OOB Publishing workflow) workflow are not being sent. Error is:

Error 530 5.7.1 Client was not authenticated

Why emails are not being sent by workflows?
