TOPICHow to remove "=?utf" from the subject of email notifications generated by Nintex Worklfow task actions.
- Navigate to Central Administration > Nintex Workflow Management > Global Settings
- Scroll to the Email Settings > Character Set section
- If the drop-down shows "not specified", we recommend you select the option "65001 (Unicode UTF-8)"
If you want the option to take effect immediately you will need to reset IIS on all the farm servers; otherwise it will take approximately 15 minutes. This should repair the email encoding issue.
