This was a question from a university in northern California deploying Office 365 for Education for faculty, staff and students.

 

Step 1 – Ensure your workstations meet the minimum Office 365 requirements

The first thing you need to do is assess what current state your workstations are in relative to the minimum requirements for Office 365.  The minimum client requirements are listed here.  You can leverage System Center Configuration Manager to scan your workstations for gaps or you can use the MAP tool. 

 

As of June 2012, here are the current minimum requirements for Office 365:

Operating systems
Windows 7
Windows Vista with Service Pack 2
Windows XP with Service Pack 3
Windows XP Home Edition is supported, but it will not support federated identity
Windows XP Media Center Edition is supported, but it will not support federated identity
Mac OS X 10.5 Leopard, 10.6 Snow Leopard


System software
Microsoft .NET Framework 3.0 (for Windows XP)
Java client 1.4.2 (for Macintosh OS X)

For additional Mac browser specific requirements visit here.

 

You need to remediate any workstations that do not meet the minimum requirements of browser, Office, or Operating System using SCCM, group policy, or other client push mechanism.

 

Step 2 – Add Office 365 updates and Sign In Assistant to workstations

After you have remediated any workstations not meeting the minimum requirements, we provide a list of required updates on the desktop specifically for Office 365 which should be in this order:

 

1) If using Lync Online, deploy Lync 2010 client or Lync 2011 for Mac client

2) Deploy Office 365 Sign In Assistant (IDCRL7):

 

Microsoft Online Services Sign-In Assistant (IDCRL7)

Windows XP SP3, Windows Vista SP2, Windows 7, Windows Server 2003, Windows Server 2008, and Windows Server 2008 R2.

User credentials are managed by Microsoft Online Services ID. To sign in to the services, users must install the Microsoft Online Services Sign-In Assistant.
