Microsoft Online offers three online services, Microsoft Exchange Online, SharePoint Online, and Office Live Meeting. Each service offering comes with its own set of bandwidth requirements. So when in the midst of planning for Office 365, it's important to understand those requirements. 

Now, when considering bandwidth requirements for Office 365 workloads, it's important to understand that there are lots of variables to consider. These variables include what services your organization plans to use, the number of client computers that you expect to be in use at any given time, and the tasks that each client computer will be performing. Other considerations include the performance of whatever internet browser your organization uses, the current capacity of existing network connections, as well as the network segments associated with each client computer. 

The organization's existing network topology and capacity of each piece of network hardware will also play roles in the planning of Office 365 workload connectivity. 

Although detailed specifications are beyond the scope of this course, more detailed information about estimating network traffic for the various Office 365 services can be found at the link on your screen.
