When using Windows 7 you may receive this error when trying to backup emails on Microsoft Exchange. The error is because TLS 1.2 is required and it is not enabled by default in Windows 7. To enable it you must set the DefaultSecureProtocols value in the registry to 800 (hexadecimal), and then reboot, as explained in this Microsoft KB article.

If you are using 32-bit Windows 7, go to the following key in the registry editor:

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\WinHttp

If you are using 64-bit Windows 7, go to the following key in the registry editor:

    HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Internet Settings\WinHttp

If the value DefaultSecureProtocols does not exist then create it as a DWORD value. Set the value to 800 (hexadecimal), which is 2048 decimal, and then reboot.

IMPORTANT: You must reboot after modifying the registry.
