Using classic Outlook for Windows in business environments
Hi WING HONGMAN
Thank you for choosing Microsoft Community.
Based on your description, don't worry, we can work together to get closer to the answer.
According to the category Outlook for Windows you posted, we can know that your problem is "Error code 0x800CCC92 occurred when receiving mail when Outlook configures your Netvigator.com mailbox" If my understanding is wrong, please feel free to correct me. I can understand that it is frustrated at times that something goes wrong, and the fact that it has not been resolved is troubling.
Although there is no fixed reason, Outlook can behave this way in many cases. Before we start looking for solutions, let's discuss these situations.
1- Whether the problem currently only happen with Netvigator Mail on Outlook. If you configure the mailboxes of other mail providers on Outlook, for example, create a new Mail account @outlook.com, configure it on the application, and then send a test email to see if it can be received normally , to see if there will be an error code 0x800CCC92 problem.
2- If there is no problem with other mailboxes, according to the error message you provided "re-authentication failed", it may be that your Netvigator Mail's mail provider has made changes to your authentication. If you are sure, check the official Netvigator Mail Set the POP3/IMAP protocol has been opened, and the server port configuration is correct, the specific situation of the authentication needs to consult the official support of Netvigator Mail.
We always look forward to your reply.
