Assigning tasks to multiple users

I have set up a meeting site, under which I have a task list webpart; two questions:

  1. I have two people assigned to one task, but the system tells me I can only have one person assigned? Is this a setting that can be changed?
  2. I have some people I want to assign tasks to that are from outside our company, if I put their name in, the system cannot identify and will not save the task. Do I have to add them as users or is there a way around this too?

thank you!

These are answers to your questions.

1) You can assign multiple people in task list, for that you do following.

Go to List settings(Tasks)-->Click on Assigned To column, then Under Allow Multiple selections, select Yes radio button.

2) If your site is Intranet then you can not assign to outside domain users.

Hope these answers helps you!!!

You can assign task to multiple users as suggested by neerubee but this may give rise to a known bug if you have not applied SP2.

Hope this helps.

Hi Neerubee,

I was having the same problem. I tried your method, but when i am doing it on my existing list, it throws an error everytime i change it to multiple user. i can not create a new task or even edit the existing one :-(

Any idea?

I am using SharePoint 2007 - I cannot find the TASK setting option to allow assigning TASKS to multiple users.

Is this feature in SP2007 ?
