Canceled SharePoint workflow continues to send reminders

This seems to be by design.

The reminders are being sent because of the tasks created when a workflow is started is still active. When you cancel a workflow it doesn't delete the tasks. You need to manually delete the corresponding tasks to stop receiving the emails.

Or you can choose "terminate the workflow". This will cancel the workflow as well as delete any related active tasks. However, this option doesnt send email to to inform the stakeholders that the workflow has been cancelled.

Workflow shows Due by 1/1/0001 12:00:00 AM

If you have configured a workflow in SharePoint 2010 and didn't provide a fixed due date (which is usually the case), the email that the workflow sends has a due date as below

Due by 1/1/0001 12:00:00 AM

Looks like a MS bug.

To fix it, follow the steps below:-

1. Open the site in SharePoint Designer.


2. On your left panel, click on Workflows


3. Click on the specific workflow and click on Edit Workflow


4. Click on the process name. Example below. In this case, click on "Approval".


5. You will get the next screen. See below. Click on "Change the behavior of the overall task process".


6. You will get the below screen


7. 


8. The value that is configured in the workflow shows 1/1/1900 8:00:00 AM but in the email we get 1/1/0001 12:00:00 AM. A bug ??


9. What I did to fix it is to change equals  to less than as shown below.
