Outlook cannot open a new form, the form contains schema validation errors.

Please advise.

Note - The user can get to the workflow when he clicks on the task from the body of the email but they are not able to utilize the Open this task Tab on the Outlook ribbon.

Answer 1

As given in the error message, the issue is with the Body column of workflow tasks list. For the approval workflow, there would be a tasks list. In the workflow task list, Body column is Enhance Rich multi-line column. Change the setting to Plain text, instead of enhanced rich text.

May be required IISreset.
