Recently, a few of our Office 365 Exchange Online clients have been receiving correspondence from Microsoft concerning the version of Outlook they are using. The message is Outlook 2007 and 2010 are out of mainstream support and their users might start experiencing reduced functionality. In this post, I’ll answer the two biggest questions we have been receiving from our clients, “What does this mean for me? and What do you recommend I do?”

What does the end of mainstream support for Outlook 2010 mean for my organization?

In general, there are two levels of end of support Microsoft products move into: End of Mainstream Support and End of Extended Support. When a product enters into the end of mainstream support it means Microsoft will no longer be releasing any non-security updates or new software design changes. The program will still function and is not a security risk to your network since Microsoft keeps releasing security fixes until the End of Extended Support date but because new features will not be added the software may not be as compatible with newer programs like Office 365 Exchange Online which is constantly being updated and improved to provide the highest level of service to subscription customers. This is why Microsoft is urging clients using their hosted email platform to upgrade their Outlook clients. Even though you will still be able to use Office 365 and connect to the platform for email, your experience will diminish over time and Microsoft won’t provide code fixes to resolve non-security related problems.

What does Databranch recommend our clients to do?

We recommend that organizations start upgrading their Outlook to a client that is still in Mainstream Support like Outlook 2013 or 2016 or start budgeting for Office upgrades. Like Windows 7, Outlook 2010 will be in Extended Support until 2020 and all users will want to be upgraded prior to the end of support date in October of that year.
