Important information – Transport Layer Security (TLS) deprecation 30 September 2022

30/09/2022 13:50:00 PM (BST)

On 30 September 2022, Microsoft will remove the connectivity for TLS 1.0 and 1.1 in NHSmail Active Directory Federated Services (ADFS).

After 30 September 2022, clients or applications connecting through these versions of TLS may not function as expected, this may take a few days to filter through the infrastructure.

We have contacted the organisations that have been identified using the old TLS connections advising them to upgrade to the later version(s).

Further information can be found in Transport Layer Security (TLS) Deprecation Guidance.
