in a way that the multiple user accounts do not see one another in say the 'employees' tab and of course each account only has access to their incoming mail and contacts?

If this can be accomplished, then for each user account to add an employee so only the original user and their employee can share information, but yet each will (again) not be able to view each other's incoming pop accounts?

Tnx.

Thanks, I just installed 2.1 and will give this a try.  When Team Management is enabled, will they see only their pop accounts as well?  Also, is there a 'users' document that explains this feature and others?   If so, if someone can post the link it would be great...I'm only stumbling across Sugar docs.
