Ceased to operate ZOHO outgoing mail on Microsoft Outlook and Outlook Express, installed on computers with Windows XP.

Hello.
On 22 February 2017 ceased to operate ZOHO outgoing mail on Microsoft Outlook and Outlook Express, installed on computers with Windows XP. When you try to send letter - a bug (0x800CCC1A) appears, but the mail of other servers (such as Gmail) is working properly.
On PCs running Windows 7 or Windows 10 everything is OK.
How can we solve this problem?
