Exchange 2010 users. Warning!

Microsoft has long planned to end extended support for Exchange 2010. The final day of any support will be the 14th of January 2020. Microsoft extended support generally covers, security updates and critical bug fixes. New features are not developed for a product which has entered extended support. These are saved for products in full mainstream support.


Exchange 2010 has been with us since it went RTM in November 2009. Building on the success of Exchange 2007, which was the first to require a 64-bit operating system. Exchange 2010 significantly enhances scalability with features such as the Database Availability Group (allowing replication of mailbox databases up to 16 times), Outlook Web App working the same in major supported web browsers and not just Internet Explorer, reduced disk costs by allowing raid-less disks and IOPS reduction of 90% from Exchange 2003 deployments.

Exchange 2010 was adopted for the email component of Business Productive Online Service (BPOS). This was the formal name of the Microsoft cloud services suite, before the launch of Office 365 in June 2011. Exchange 2010 supported hybrid integration, with Exchange Online service to allow native migrations of mailboxes and archives.

Why is no support a problem?

With the removal of the last level of support, elements such as Office 365 attribute editing become unsupported and the hybrid wizard app will no longer support Exchange 2010. This means certificates or configuration changes may no longer possible. It should be noted that Microsoft are not expected to actively block connections of versions.

On the security front, TLS 1.0 was becoming mainstream as the older SSL3 was being compromised and deprecated. That was over 9 years ago, and cryptographic standards have been overhauled making, TLS 1.2 the default expected standard, which was only supported by Exchange 2010 in the last 12 months.


Most of our customers are now migrating/adopting Office 365 (Exchange Online). A supported Exchange hybrid makes this migration possible using native tools.

There are dozens of clients require the deployment of on-premises Exchange environments. We have deployed this for customers varying in size from a few hundred mailboxes to 40,000 mailboxes. Exchange 2019 was released in October 2018 and Microsoft are expecting to release another version of Exchange around 2022.
