How to Fix Outlook 0x8004102A Send / Receive Error

A few users are facing sync issues in Outlook. The most common sync error is “Task reported error (0x8004102A) Error with Send/Receive. There was an error synchronizing your folder hierarchy. Error 80041004”. Basically, this error occurs when there is no sync between the Outlook mail (the web app) and Microsoft Outlook (the desktop app) in the Exchange Mail Server. Due to this users cannot send or receive emails from their Outlook.com to the Outlook server. The sync issues happen when the Outlook account settings are changed, credentials changes, certificate issues, cache issues, file corruption, using older versions of Outlook, etc. In this article let us see the different methods to solve the sync issues in Windows 10.
