Office 2010 & 2013 End of Support with Microsoft 365

Microsoft Office Logo

If you are a subscriber to a Microsoft 365 plan (formerly called Office 365), and have Office 2010 or Office 2013 installed on your local computer(s), take note of this upcoming deadline.  Microsoft have advised they will no longer be supporting connectivity of these versions of Office to Microsoft 365 cloud services as of Oct 13, 2020.


While Microsoft will not actively take measures to block connections to  Microsoft 365 applications, with these older versions of Office attempting to connect to a modern, always up-to-date data cloud service, you may experience performance and reliability issues. There will also come a time when connectivity to Microsoft 365 Email will cease to work, without any  advance notice.  One day Outlook will just no longer be able to connect to your mailbox, leaving you without the ability to send or receive Email using Outlook, or possibly even access email you have already viewed in Outlook.

There are further implications relating to security vulnerabilities for Office 2010 after October 13, 2020, which you can read about in our blog here.


After October 13, 2020, in order to ensure full functionality and connectivity to Microsoft 365 cloud applications, you will require a Microsoft 365 subscription which includes the locally downloadable Office suite, or a perpetual Office license version that is still in mainstream (not extended) support. This currently includes Office 2016 and Office 2019.

If you have any Office 2010 or 2013 versions installed on your network and would like to understand your upgrade options, please give us a call.
