Outlook 2010 won't stay connected to the server

Hi! I'm a new member today, although I have found answers here before I think I have a new issue.
In my office I have 6 computers running from one router. 3 of those machines are the exact same machine all bought and installed at the same time. 2 of those machines are having issues with Outlook 2010 staying connected to the server. I have tried everything I can think of with no solution. Help me! rolleyesrolleyes I need an icon showing pulling my hair out!

 

Are you sure it's the server and not the router they are disconnecting from?

 

yes, still have internet access. I figure it is something very simple that I overlooked but won't be back into the office until tomorrow morning. I was looking for a difficult solution and I think it is something as simple as working offline. I hope so anyway. Thank you!

 

Thanks for you help! I have resolved the problem. It was working offline and wouldn't stay connected when I clicked to work online. After going through the motions of turning the button off and restarting a couple of times I have had no problem.

 

Crazy I have a new issue but can't find where to post a new thread?!?!?
