Question

SharePoint 2013 workflow sending two emails when task is assigned

Frank Martin 501

I created a SharePoint 2013 type workflow (using SharePoint 2016) in SharePoint Designer. When a task is assigned then user is receiving two emails. One email is my custom email which I have set in workflow and other is system generated. The other email seems like the one which is sent by SharePoint when you are subscribed to Alerts on a list. But the thing is I haven't done any subscription so why users are receiving this email and how to make it stop?

This is a Dev environment and I have just created this site and workflow.

Hi @Frank Martin , there is one more setting to check in case it helps:

Please open the Workflow task list via SharePoint Designer 2013 > Workflows > the workflow you are using > Open task list under Customization > Preview in Browser on ribbon.
Navigate to LIST > List Settings > Advanced settings > E-Mail Notification and switch this setting to No.

Please check and confirm:
There is an option “Modify my alert settings” in the email (also can be found in the screenshot you provide), which will bring you to the “My Alerts on this Site” page directly when being clicked on.
Please click on the link in the email and see if there is any alert listed on this page. Delete the alert if any.

You may also check the alerts on user’s behalf as a site collection administrator via Site Settings > User Alerts (under Site Administration).

I clicked on Modify my alert settings as a user but I can see no alerts are defined.
I went into User Alerts as Site Collection Administrator and can see no alerts are defined for anyone.

@Frank Martin
If no alert is set in this site, next step would be to check the workflow instead.
Please check as following:

Can you reproduce this issue if you assign the task to other users? Try using another user account in the task action and see the result.

What Start Options do you choose for this workflow? If you have set it to run on both item creation and modification, here is a post with similar scenario you can refer to: Solved: SharePoint 2013 custom workflow generates duplicate email notifications.

You can modify the workflow and add “log to workflow history” action under every step to track the workflow process, see if you can find anything usual in this process.
You can also share the workflow configuration in this thread if necessary.
