It turns out I can't use email distribution lists in SP workflow (complicated), so I had to create SP Group and re-add all the recipients. However, I ran into several major nuances:

  • Receipts are seeing a WALL of individuals in the "To:" line. In the past in Outlook it looked proper, like only the email distro was showing ex. "National List; Support; boss@company.com", etc.
  • Many users are seeing duplicate emails because they are listed in several of these email groups.

Is there a solution to this?

P.S. Your help is appreciated.


In the SharePoint 2013/2016/Online workflow, you can't send an email to a untrusted account which means recipient is not a valid SharePoint User/Group.

You will see a warning if you want to add a group. enter image description here

To send an email to your distribution group you have to enable the Security group settings. And then you need to add this group to SharePoint site to make a valid SharePoint user.

You can update the group setting from your Active Directory server.enter image description here

  • Would this work for clients that use Office 365 for SP and email? I only ask because our administrator said that "we'd have to recreate main group [email distribution list] and subgroups as office 365 Groups" – Humble Val Jun 15 '17 at 23:20
  • This works SharePoint Online (O365) site as well which is currently settings in our environment – Venkat Konjeti Jun 16 '17 at 2:17
