So what is happening in 2020?
On 14th January 2020 Microsoft will begin ending support for many of its legacy products, this means you will no longer receive security updates. Continuing to use affected software after this date will put you and your business at greater risk of security breaches and data loss.
What you need to do BEFORE 2020
If you are currently using any of the affected products from Microsoft you will either need to upgrade/update your software to newer supported versions (.i.e Office 2016/365) or it may be required to upgrade the hardware as well (.i.e upgrading from Server 2008 R2 to Server 2016/2019)
