Supported OS and Office version with Office 365 (and how to find them)

In a very recent discussion on linkedin an Office 365 Customer was complaining about the fact that his Office 2007 was not working properly with Exchange Online after his migration. When I tried to explain that an upgrade of his Office & OS Versions (he was still running XP) was something he might want to consider, he wasn’t very understanding -to put it mildly.

I started thinking about a reason why still so many people are clinging on to their Windows XP and their Office 2007, … The most common answers are “It just works, why would be change”, “I love XP, I don’t want to change”, “Microsoft is all about making money and we have to provide it”, … But actually it’s deeper than that. It’s a human thing. It has nothing to do with XP, Office365, Office … It’s because those companies, the people leading those companies are Laggards on the curve of the Technology Innovation Lifecycle.


How do you have to read this graph? Let’s translate this to Windows & Office

Innovators: Windows 8.1 since beta, Office 2013 SP 1 Technical Preview

Early Adopters: Windows  8.1 since RTM, Office 2013 since RTM

Early Majority: Windows 8, Office 2013

Late Majority: Windows 7, Office 2010

laggards: Windows XP/Vista, Office 2007

One typical thing about laggards, they need to see the technology proven a lot of times, they might even be more willing to go to Windows 7 than Windows 8. Now you know this you can actually adept your Sales & Proposition model to this. The companies still on XP now are in that last category. One little tip, in every laggard company there are innovators, the million dollar question is how to find them and if they have authority to make decisions.

But let’s assume your cracked the coconut, you can upgrade your client or your company to a supported OS & Office version. What are the supported versions where you should lead your customer too? The next list is based on my experience and not the Microsoft Official List that you can find here:

Second part is how to find these systems that you have to migrate. In a SMB with 10 computers, no problem. If you need to do that for 250 computers you need some kind of tool. The toolkit you can use is the Microsoft Assessment and Planning Toolkit. .. In one of the next days we’ll cover how the Microsoft Assessment & Planning Toolkit works in depth.
