MC357842  – After five years of Mainstream Support, and five years of Extended Support, Office 2013 will reach the End of Extended Support on April 11, 2023. Per the Fixed Lifecycle Policy, after this date security updates for Office 2013 will no longer be available. Microsoft recommends you upgrade to Microsoft 365 Apps, which includes the Office apps you are familiar with (such as Word, Excel, PowerPoint, and Outlook).

Note: If you don’t have Office 2013 deployed in your environment, you can safely disregard this message.

When this will happen:

Office 2013 will reach the End of Support on April 11, 2023.

How this will affect your organization:

After Office 2013 reaches the end of support, Microsoft won’t provide any new security updates, and the continued use of Office 2013 after April 2023 may increase your organization’s exposure to security risks or impact your ability to meet compliance obligations.

Also, if you connect to Microsoft 365 with an Office 2013 client, you might experience performance or reliability issues. Since October 2020, Office 2013 is not a supported client to connect to Microsoft 365 services. These are the client versions of Office that are currently supported for connecting to Microsoft 365 (and Office 365) services (learn more):

  • Microsoft 365 Apps
  • Office LTSC 2021
  • Office 2019
  • Office 2016

What you need to do to prepare:

Please start upgrading to Microsoft 365 Apps, which is designed to receive regular updates, and will help you stay current by getting security updates and our latest features.

Alternatively, if your organization requires a static, unchanging product, consider moving to Office LTSC 2021. When evaluating your options, keep in mind the end of support dates for Office clients connecting to Microsoft 365 services (learn more). Here are some resources to help you plan your upgrade:
