Minimum TLS version enabled (obsolete)

Supported on Microsoft Edge version 77-97, Windows 7 or later

155.0.4283.62

What it does

OBSOLETE: This policy is obsolete and doesn't work after Microsoft Edge 97. This policy was removed in Microsoft Edge 98 and is ignored if configured. Sets the minimum supported version of TLS. If you set this policy to 'tls1.2', Microsoft Edge shows an error for TLS 1.0 and TLS 1.1, and the user won't be able to bypass the error. If you don't configure this policy, Microsoft Edge still shows an error for TLS 1.0 and TLS 1.1 but the user will be able to bypass it. Support for suppressing the TLS 1.0/1.1 warning was removed from Microsoft Edge starting in version 91. The 'tls1' and 'tls1.1' values are no longer supported. Policy options mapping: * TLSv1 (tls1) = TLS 1.0 * TLSv1.1 (tls1.1) = TLS 1.1 * TLSv1.2 (tls1.2) = TLS 1.2 Use the preceding information when configuring this policy. Example value: tls1

The OMA-URI is an inferred ADMX-backed Policy CSP candidate derived from the source ADMX file name and policy name.
Some Microsoft policies use built-in Policy CSP pages whose area names don't match the ADMX file name, so verify the candidate against Microsoft Learn before deployment.
The generated payload is incomplete because one or more ADMX element values were not supplied: SSLVersionMin
