Why can't I remove a user from my project? I get an error message when trying to remove a user from my project. It says "Unable to remove all team members".
If the person that you're trying to remove is the only assignee on one or more tasks, you will see the following popup:
Click the View Tasks link to see which conflicts need to be resolved. Once all tasks are reassigned to someone else, you should then be able to remove the user without issue.
This popup will keep appearing until you have reassigned all impacted tasks.
