I’m having issues making UiPath Send emails using SMTP with an Exchange Server.
The customer environment only allow us to use non-encrypted, non-authenticated SMTP protocol, relay privileges is granted by IP Address. We tested SMTP features using a full e-mail client in the robot machine and mails are sent, so there are no networking issues, blocked ports, etc.
When using the SMTP send mail activity in UiPath we get the following error:
Main has thrown an exception
Source: Send SMTP Mail Message Message: No compatible authentication mechanisms found. Exception Type: NotSupportedException System.NotSupportedException: No compatible authentication mechanisms found. at UiPath.Mail.Activities.SendMailActivity.EndExecute(AsyncCodeActivityContext context, IAsyncResult result) at System.Activities.AsyncCodeActivity.System.Activities.IAsyncCodeActivity.FinishExecution(AsyncCodeActivityContext context, IAsyncResult result) at System.Activities.AsyncCodeActivity.CompleteAsyncCodeActivityData.CompleteAsyncCodeActivityWorkItem.Execute(ActivityExecutor executor, BookmarkManager bookmarkManager)
Any idea on how to use plain (non authenticated) SMTP from UiPath?
