Microsoft Online Services currently offers three online services: Microsoft Exchange Online, SharePoint Online, and Office Live Meeting. Each of the services has its own bandwidth requirements.

There are many variables to consider when estimating network traffic. Some of these variables are:

  • The services that your company has subscribed to
  • The number of client computers in use at one time
  • The type of task each client computer is performing
  • The performance of your Internet browser software
  • The capacity of the network connections and network segments associated with each client computer
  • Your company’s network topology and the capacity of the various pieces of network hardware
