I created a flow 'when item is created or modified' to send email to user who is listed in the 'Assign To' column in SharePoint. The flow worked fine until my manager asked me to make the 'Assign To' column in SharePoint multi-select. So I updated it. Now my flow does not work.

How can I set my flow to send email to all persons listed in the 'Assign To' column in SharePoint?

Thanks enter image description here

Try this:

  1. Initialize a blank string variable
  2. Append the variable with the "Assigned To Email" field. This should add it into a new "Apply to Each" action.
  3. After the new Apply to Each action, add the variable to the "To" field of your "Send an email from a shared mailbox action.

  • I am getting an error. Here's the error: ExpressionEvalualtionFailed. The execution of template action 'Apply_to_each_2 failed the result of the evaluation of 'foreach' expression '@triggerOutputs()?(body/AssignedTo']' is of type 'Object'. The result must be a valid array. Jun 1, 2021 at 15:25
  • Hi Aleshia Thompson. "Apply to each 2" error? Can you tell me your whole flow process? This can help us solve the problem better. Jun 2, 2021 at 0:46
  • After more searching, I found that I had to add the 'Compose' action to compose the output and return the json code. I added this to what you provided and it worked. Thanks so much for putting this in plain language. I appreciate that. Jun 5, 2021 at 20:15
