Update to enable tls 1.1 and 1.2

Run Type "inetcpl.cpl" and click OK In the Internet Properties panel, select the tab " Advanced", and in the Settings, Security section mark to activate the boxes [" Use TLS 1.1", " Use TLS 1.2"] Important: Before you do any change on the Windows registry, it strongly recommended to back it up. Right-click Windows button and select Run Type " regedit", and click OK Then go to " Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols", and create one key and two DWORD(32-bit) values, as the image below shows. Key/Key Values Name Value key TLS 1.2 DWORD(32-bit) DisabledByDefault 0 DWORD(32-bit) Enabled 1 Now, you can exit the registry and restart your machine.

In this article Summary: This article describes how to enable Transport Layer Security (TLS) protocol versions 1.1 and 1.2 onwards in Office Online Server. To enable TLS protocol versions 1.1 and 1.2 onwards in your Office Online Server environment, you need to configure settings on each server in your Office Online Server farm. The configuration process involves setting a number of registry keys to turn security protocols on or off. While you can make these updates to the registry manually or by using a .reg file, we recommend that you create group policy objects to manage these settings, particularly if you are configuring these protocols across your organization. The basic steps covered in this article are: • Enable strong cryptography in .NET Framework. Note Using TLS 1.1 and TLS 1.2 onwards with Office Online Server requires that TLS 1.1 and TLS 1.2 onwards be enabled on Windows Server for each computer in your Office Online Server farm. They are enabled by default for Windows Server 2012 R2. Follow these steps on each server in your Office Online Server farm. Enable strong cryptography in .NET Framework 4.5 or higher Note As of the July 2021 cumulative security update ( Using TLS 1.1 and TLS 1.2 onwards with Office Online Server requires strong cryptography in .NET Framework 4.5 or higher. To enable strong cryptography in .NET Framework 4.5 or higher, add the following registry keys: Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\.NETF...

Update: please see our official documentation which is now available on this subject: Overview In part 2 of our Exchange Server TLS Guidance series we focus on enabling and confirming TLS 1.2 can be used by your Exchange Servers for incoming and outgoing connections, as well as identifying any incoming connection which is not utilizing TLS 1.2. The ability to identify these incoming connections will vary by Windows Server OS version and other factors. Part 2 will not cover disabling TLS 1.0 or TLS 1.1, nor disabling older cipher suites from being used. Part 3 of the TLS guidance series will go into detail on those topics. Assumption For Part 2 of our TLS guidance series we assume you have already audited your on-premises Exchange Servers and applied all updates called out in Enabling TLS 1.2 The method used to enable TLS 1.2 varies by the version of the Windows Server operating system. Some versions of Windows Server have TLS 1.2 enabled by default while others do not. Our steps will, regardless of the OS’ default state, configure TLS 1.2 so it is enabled and available for incoming (Server) connections and outgoing (Client) connections. From part 1 you should be familiar with the various components Exchange Server relies on such as Schannel, WinHTTP and .NET. Unless stated otherwise the same registry paths are used across all supported Windows Server operating systems. Enable TLS 1.2 for Schannel All Windows Server versions TLS protocols are enabled or disabled in Windows ...

Hi This update -https://support.microsoft.com/en-us/kb/3140245 is aimed at making it possible to deafult set Windows 7 to a particular TLS protocol 1.1 or 1.2, however the setting, as we understand it, it applies after install 1.0 across all browsers regardless of how advanced they are. Can anyone confirm that this is actually what happens?! Kind regards Jules Murray

Enabling TLS 1.2 on Windows servers involves the following steps: • Start by backing up the Registry: Open regedit and navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL. Go to File > Export and save the backup. • Disable TLS 1.0: Within the Protocols section, locate TLS 1.0 > Client and modify the Name Enabled to 0, effectively disabling TLS 1.0. Please refer to the accompanying images for visual assistance. TLS 1.0 > Client modify Enabled to 0 TLS 1.0 > Server modify Enabled to 0 • Disable TLS 1.1: Follow similar steps as above for TLS 1.1. Within the TLS 1.1 > Client section, change the Name Enabled to 0, disabling TLS 1.1. In the TLS 1.1 > Server section, modify the Name Enabled to 0, effectively disabling TLS 1.1. • Enable TLS 1.2: To enable TLS 1.2, modify the Enabled value to 1. Under TLS 1.2 > Client, set the Enabled value to 1 in the HexCode format (1 will be automatically converted to HexCode after saving). In the TLS 1.2 > Server section, set the Enabled value to 1.

In this article, we will look at how to enable the Transport Layer Security (TLS 1.2) protocol on different Windows versions, including cases for .Net and WinHTTP applications. TLS 1.0 and TLS 1.1 are deprecated protocol versions. If you have migrated all your services to TLS 1.2 or TLS 1.3, you may disable support for legacy TLS versions on your Windows servers and clients ( Without these updates, Outlook on Windows 7 will fail to connect to a modern e-mail server with an error: • Restart your computer. These registry options are described in the article Update to enable TLS 1.1 and TLS 1.2 as default secure protocols in WinHTTP in Windows ( The following REG_DWORD registry items will appear on your computer in HKLM\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Client\ and HKLM\...Protocols\TLS 1.2\Servers: • DisabledByDefault = 0 • Enabled = 1 In order to use TLS 1.2 by default for WinHttp API apps, add the DefaultSecureProtocols = 0x00000A00 REG_DWORD parameter to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\WinHttp (on Windows x64: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Internet Settings\WinHttp). Here are the possible values of DefaultSecureProtocols option which defines allowed protocols for WinHTTP connections: • 0x00000A0 – a default value allowing SSL 3.0 and TLS 1.0 for WinHTTP only • 0x0000AA0 — allows using TLS 1.1 and TLS 1.2 in addition to SSL 3.0 and TLS 1.0 •...
