There are occasions when you click on a new task link on the 'Communications' template that you may see this message.
To overcome this the practice needs to have a user group named exactly the same.
To create a new group
- Go to 'Workflow > Task List > click on settings > User Groups
- Click on 'New Group' and call it 'Administration'
- Click on the new group title and select from the staff list on the right who you want to be in that group
You cannot amend the name of an existing group so if you already have a group with a similar name, to avoid any duplication, you should consider deleting any redundant groups.
