Dear Primary/Local Administrator,
Important Information – Outlook 2010 end of life and Transport Layer Security (TLS) deprecation.
Outlook 2010 end of life, October 13, 2020
From October 13, 2020, Microsoft will no longer support Outlook 2010, including all service packs.
What does this mean?
After October 13, Microsoft will no longer provide organisations with:
- Technical support for issues
- Bug fixes for issues that are discovered
- Security fixes for vulnerabilities that are discovered
While connections will not be actively blocked, Microsoft will not be testing Outlook 2010 against any new product releases – meaning functionality could be lost at any time.
Further details can be found in the Office 2010 end of support roadmap.
What action do we need to take?
It is strongly advised that organisations choose from one of the following options to minimise potential disruption after October 13.
There are two main options available:
- Organisations can utilise the National O365 (N365) deal to procure Apps for Enterprise licences (previously known as Pro Plus) and onboard them to the central NHSmail tenant. Further information on how to onboard licences can be found in the onboarding guidance for Local Administrators.
- Organisations can procure Office 2013, 2016 or 2019 directly through a Microsoft reseller. Please consider end of life support dates for other Office suites when making your upgrade decision.
Transport Layer Security (TLS) deprecation, October 15, 2020
Microsoft will start removing access within O365 and Exchange Online for connectivity using TLS versions 1.0 and 1.1 on 15 October 2020. This means any clients, devices, or services that connect to Office 365 through TLS 1.0 or 1.1 will stop working.
To ensure that there is no impact, all client machines and applications using NHSmail must support TLS 1.2.
What are we asking you to do?
It is important that you carry out a review of your organisation’s use of TLS and upgrade to supported versions where appropriate.
Please see our TLS deprecation support page for more information and guidance.
Please note – although this change is driven by Microsoft, where we are able to identify unsupported TLS versions, we will be contacting organisations to let them know.
If you have any questions, please email email@example.com.
Thank you for your assistance
