# Before you can manage all of Office 365 from a single instance of Windows PowerShell, consider the following prerequisites:

# The Office 365 work or school account that you use for these procedures needs to be a member of the Office 365 Global admin role. This a requirement for Office 365 PowerShell, not necessarily for all other Office 365 services. For more information about permissions in Office 365, see Permissions in Office 365.

# You can use the following 64-bit versions of Windows:

# Windows 8.1 or Windows 8

# Windows Server 2012 R2 or Windows Server 2012
