Re: Send email to "Assigned To" user - Only Once!
Hi @Anonymous,
Do you want the flow would only run when the "Assigned To" field changes from blank to populated or from one user to another?
If you want the flow would only run when the "Assigned To" field changes from blank to populated or from one user to another that means you want the flow would only run when the "Assigned To" field changes,and the the flow wouldn't run when only other field changes.
The trigger "when a special field is changed" is not supported in microsoft flow currently,
If you would like this trigger to be added in Microsoft Flow, please submit an idea to Flow Ideas Forum:
https://powerusers.microsoft.com/t5/Flow-Ideas/idb-p/FlowIdeas
As an alternative way, you could add a Yes/No type column "AssignedToIsChanged" in your sharepoint list, and every time when an item is modified, if the "Assigned To" field is modifed, then you must set the "AssignedToIsChanged" field to "Yes",if the "Assigned To" field isn't modifed, then you must set the "AssignedToIsChanged" field to "No".
So you could add a Condition under the trigger to check if the "AssignedToIsChanged" field is equal to true, if the "AssignedToIsChanged" field is equal to true, that means the "Assigned To" field is modifed, so you could send the email inside the If yes branch, else, do nothing inside the If no branch.
Best regards,
Alice
