Microsoft have announced that from 14th October 2025 they will no longer provide security updates or functionality and compatibility updates for Microsoft Office 2016 and 2019,  or for the 2016 and 2019 versions of individual Office apps such as Word, Excel, PowerPoint, Access, Outlook, Project and Visio.

 

What does this mean?

As Microsoft will no longer provide security updates for these versions there is a greater IT security risk associated with continuing to use them, and their functionality and compatibility with other services will also be impacted over time.

 

What do I need to do?

For the security of your data and College IT systems if these older versions are still installed on your computer(s) then it's important that you uninstall them and instead install the Microsoft 365 versions which can be done by logging in at http://office.tcd.ie, choosing Apps on the left menu and then choosing 'Install Apps' from the top right of the screen.

 

If you need any assistance or more information in relation to the above please contact the IT Service Desk at +353-1-8962000 or email itservicedesk@tcd.ie.
