Enable 3DES cipher suites in TLS (obsolete)
Verified with Microsoft Edge 152.0.4191.53 — updated on July 10, 2026
Supported on: Microsoft Edge version 93-96, Windows 7 or later
Path in the GPO console
Computer Configuration\Administrative Templates\Microsoft Edge User Configuration\Administrative Templates\Microsoft Edge Description
OBSOLETE: This policy is obsolete and doesn't work after Microsoft Edge 96. This policy was removed in version 97 after 3DES was removed from Microsoft Edge. If you enable this policy, then 3DES cipher suites in TLS are enabled. If you disable this policy, then the 3DES cipher suites in TLS are disabled. If the policy is unset, 3DES cipher suites are disabled by default. This policy may be used to temporarily retain compatibility with an outdated server. This is a stopgap measure and the server should be reconfigured.

Software\Policies\Microsoft\Edge Value name: TripleDESEnabled
Enabled: TripleDESEnabled = 1
Disabled: TripleDESEnabled = 0
Export Builder
BETAConfigure the state, scope and options, then generate .reg, PowerShell, Intune and SCCM outputs — or add the setting to a multi-setting collection.
These exports write the registry — this is not a managed GPO. ⓘ
Applying both scopes creates an ambiguous configuration (computer takes precedence over user). Only do this intentionally.
