What this means for your customers
There are two elements that go into Microsoft’s official support: technical assistance provided to users upon request, and general maintenance of the software. The first element likely seems insignificant for your customers (they might simply come to you with their issues), but the discontinuation of the second constitutes a major problem that will only get worse.
Even after years of work, Exchange 2010 isn’t perfect. Outside of systems developed to perform specific life-or-death functions, code never is. That means there are probably bugs that are yet to be discovered and security vulnerabilities that still haven’t been patched. And once Microsoft stops even trying to update it, hackers will see greater value in searching for those issues.
There’s also the inevitability that its basic functionality will start to degrade in the near future. Cross-system compatibility is increasingly important, and it’ll only get more inconvenient to be reliant upon a solution that doesn’t really work with anything else.
It certainly isn’t very appealing compared to the utility and efficiency of the increasingly-dominant cloud system model. Moving your customers to the Microsoft cloud with either Office 365 or Microsoft 365, means they will benefit from the massive $1billion investment into cloud security that Microsoft is making every year as standard.
The associated cost of ownership for your customer to maintain this on-premise environment can be eye-watering and be massively reduced when they’ve migrated to the cloud.
The ability for you to remotely triage and fix issues, without having to physically wire into an on-premise service can be game-changing for your customers business continuity, and for the hours you invest in travelling. These hours can be spent nurturing, developing and upselling new cloud-based services, that will take your customer to new operating efficiencies.
For all these reasons (and more), it’s clearly a sensible move to consider replacing Exchange 2010 as soon as possible, and at least start preparing to swap it out for a more modern solution with years of support ahead of it.
