On 01-Jul-2019 we retired some old encryption protocols that are used when email programs connect to our servers. If you have an older email program this might affect you.

We ended support for the outdated encryption methods (TLS 1.0 and 1.1) to ensure that we provide the latest and most secure encryption between your email program and our service. We now require TLS 1.2 as a minimum.

By default TLS 1.2 is not enabled on Windows 7, but it does support it and you can easily enable it using the instructions below.

Update Windows 7

Before you begin, update Windows 7 to ensure it has all the latest updates, particularly Service Pack 1.

Edit the Registry settings

1. Click on the Windows button and then choose Run.

Enter “regedit” in the field as shown above and click OK.

This will open the Registry Editor.

2. You will see a list of keys (they look folders). Open the keys in this following order:

HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > Control > SecurityProviders > SCHANNEL > Protocols

The two images below show you what this will look like. The second image is where you want to be as this is where you will make some changes.

First part of the key list
This is the section you will make changes to

3. Right-click on “Protocols” and choose the option New followed by Key as shown below.

You will see a new entry under SSL 2.0 that says “New Key #1” and you need to rename this key “TLS 1.2”. You should just be able to type this as the key name will be in edit mode already, but if you need to right-click on the new key and choose Rename. You should now have what is shown in the image below.

4. Right-click on the new key you just created and choose New followed by Key. This is just the same as you did in the previous step.

As before, the new key will be called “New Key #1”. This time rename it to “Client”. You should then have the key arrangement shown below.

5. Right-click on the new key you called “Client” and choose New and then DWORD (32-bit) Value.

This will create a new value in the window to the right called “New Value #1”. Right-click on this entry, choose Rename, rename it to “DisabledByDefault” and press enter.

You should now have the arrangement shown in the image below. If you do, proceed to step 6.

6. Now closed the registry editor and restart your computer. A restart isn’t always required, but is recommended.
