I have a workflow created using App Step and I am able to send the mail for a particular user, but when I try to send the mail for a group the workflow gets cancelled and returning the error as:

RequestorId: e2e82bc4-4c1f-b170-af9b-f98ba870f7f6. Details: System.ApplicationException: HTTP 401 {"Transfer-Encoding":["chunked"],"X-SharePointHealthScore":["0"],"SPClientServiceRequestDuration":["31"],"SPRequestGuid":["3743add9-0c59-4341-af5a-03bb570526cf"],"request-id":["3743add9-0c59-4341-af5a-03bb570526cf"],"X-FRAME-OPTIONS":["SAMEORIGIN"],"X-Content-Type-Options":["nosniff"],"X-MS-InvokeApp":["1; RequireReadOnly"],"MicrosoftSharePointTeamServices":[""],"Cache-Control":["max-age=0, private"],"Date":["Thu, 21 Jul 2016 11:42:18 GMT"],"Set-Cookie":["WSS_KeepSessionAuthenticated={398aa3b9-3eed-448c-89b6-07651a321a9e}; path=/"],"WWW-Authenticate":["NTLM"],"X-AspNet-Version":["4.0.30319"],"X-Powered-By":["ASP.NET"]} at Microsoft.Activities.Hosting.Runtime.Subroutine.SubroutineChild.Execute(CodeActivityContext context) at System.Activities.CodeActivity.InternalExecute(ActivityInstance instance, ActivityExecutor executor, BookmarkManager bookmarkManager) at System.Activities.Runtime.ActivityExecutor.ExecuteActivityWorkItem.ExecuteBody(ActivityExecutor executor, BookmarkManager bookmarkManager, Location resultLocation)*

But the workflow is running as expected outside the App Step even for SharePoint group.I am not understanding where I have missed.

  • Is that and AD group or SharePoint group? Jul 21, 2016 at 13:16
  • It is a sharepoint group

  • Then it should be cancelled. As per my knowledge the Workflow Send Email tries to find the email address of the specific user. While sending email to a group do not provides a valid email address and a valid user type. Try creating an AD group and then add all the target users in that group. Give it a try sending email to that security group. Aug 1, 2016 at 19:41

You cannot send mail to the SharePoint group. You can send mails only to users and distribution group(AD group).

Hope this helps.
