I’m not 100% sure this will work, but its worth a try. 

1. Your snippet should take the resulting array and update a field in a UI Only model with that value  (Look for the documentation on updateRow here )

2.  Use the DataSource action for your Outlook data source that sends a message.  The “TO” property will take a semicolon separated list of email addresses.  If your UI Only field has that list you can use merge syntaxt to pass it in. Somthing like this:  {{$Model.UiModelName.data.0.EmailAddressesFieldName}} 




Good luck with this!  

I was able to get this working, thank you Rob for your direction! Here’s a brief summary where I landed up to get it working:

• 
  

  Created a UI Model with UI Field.

  
  


• 
  

  Created global action that runs the Email Array snippet to populate the UI Model/Field, and then creates new row in Draft model via PopUp- populating the “ToRecipients” field with the string in the UI Field. Subject and Body fields are editable for user input

  
  


• 
  

  Added a button to the Draft model PopUp that saves Draft and runs an Outlook 365 Action : Send Draft

  
  

**Snippet: **

// Get the Email of the selected items as an Array

_var emailArray = skuid.$.map(argumentsu0].list.getSelectedItems(),function(item){ _

_ return item.row.Email; _

});

// Convert array to String

var emailString = emailArray.join(‘;’);
var $ = skuid.$,

_ model = skuid.model.getModel(‘UIEmAd’),_

_ row = model.getFirstRow();_

_ model.updateRow(row, {emadr:emailString}_);

Thanks for documenting your solution back to the community.  Sharing the riches!!!
