Multiple Users, Account Security, Admin powers

[eztweaks]

Hey guys..new to the forum...hoping you can help..

I am going to try to be as short and concise as possible on this, while asking some fairly complicated questions. But first our specs:

Users: 10
Computers:11 (not including the server)
Emails: 10 employee and 4 departmental

User Computers:
Microsoft XP Professional Service Pack 2
Microsoft Outlook 2007

Server:
Windows Server 2003 R2 Standard Edition Service Pack 2

Here are the tasks that I need to perform:

1. Set up each user in Outlook
2. Make Outlook follow each user depending on what computer that user logs into the system on.
3. Other users can not access another Outlook account
4. Set permissions regarding calandar events (some can add events, some can not, some can add events to another users calandar)
5. Instant messaging between users

The Problems:
1. It appears that I need to go to each computer and set up each user and each email which is extremely time consuming. There has to be an easier way.
2. I can not find a way to make Outlook follow each user.
3. If I set up Outlook on a computer on Sally's account when she logs off Bill can log into his account and Outlook is automatically still in Sally's account.
4. I can not find a way to set permissions (not sure if this exists, but I would think it should)
5. In the past Instant Messaging was set up on the old system, since the update the person that set it up has left the company and I have no idea where to look.

That is everything I can think of right now. Thanks in advance for any help

I forgot to mention that the profiles on the server are already set up as "roaming" profiles. Meaning "My Documents" is not specific to one computer, but specific to the user.
