I've seen on message boards that you can't share tasks in Outlook for Mac 2011, and in this conversation they suggest connecting as a delegate, but the information they link to no longer exists. 

My ultimate goal is to have a shared task list between my assistant and myself. It'd be great to be able to categorize when it's a task for my assistant and when it's one I need to complete. It'd be great if we could both contribute to this list. 

I have no idea what connecting as a delegate means, but if that's the way to do it then some guidance on what that means and how it works in relation to tasks would be great. 

Thanks for any input!
