I am trying to create a workflow (According to the "Approval - Sharepoint 2010" template) and to activate "Enable Content Approval" in it, this works fine, but it doesn`t do anything.

Some research resulted in the site feature "Workflows can use app permissions" to be nessessary to use this feature.

So I go to the site that contains the library, go to "Site settings", "Manage site features", look for the feature and click the Activate-button.

Doing that results in this error message

An unexpected error has occured.

Using the Correlation ID I was able to find this stack trace, which seems to maybe explain why it does not work:

Unexpected Microsoft.SharePoint.WorkflowServices.NotConnectedException:
Exception of type 'Microsoft.SharePoint.WorkflowServices.NotConnectedException' was thrown.

at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

Sadly I do not know what this means, and I couldn`t find anything on Google.

I hope someone can explain what this means, or maybe even tell me, how to solve this problem.


It looks like you have not setup or completely configured the Workflow Manager. The below link is for SP2013, but it will work for SP2019.

  • We haven´t actually managed to install the workflow manager, we are now looking for a sharepoint-external solution. I sadly don´t know if this answer was helpful, but it was the most helpful answer, which is why I accept this answer now. – user84581 Jun 20 '19 at 9:37
