Adding NetEase corporate mailboxes to Outlook is always unable to verify the security certificate used by the server you are connected to

The first step, according to the following steps, use Outlook to add NetEase corporate mailbox.

The second step is to set the mail access protocol to IMAP in the advanced settings.

The difference between IMAP and POP:

1. IMAP is the abbreviation of "Internet Mail Access Protocol".

  POP3 is the abbreviation of "Post Office Protocol - Version 3". It is the third version of the post office protocol, which stipulates the protocol for personal computers to connect to the mail server of the Internet and download e-mail.

2. IMAP does not need to download all the mails on the server (download according to actual needs), but can operate the mails through the mail client.

   POP3 allows downloading mail on the mail server (download all unread emails), and delete mail on the mail server when the mail is sent from the server to the computer (currently many mail servers support "download mail, do not delete mail, or send a reminder").

3. IMAP provides two-way communication between WebMail and the mail client. The operations on the client (such as: read, delete, move mail, etc.) will be fed back to the mail server. When operating mail on WebMail, it will also be fed back to the mail client. (That is, the emails and statuses viewed by logging in to the mailbox on the email client and browser are consistent).

  POP3 operations on the client (such as: read, delete, move mail, etc.) will not be fed back to the mail server, such as: when moving the mail on the client to other folders, the mail server will not move these at the same time mail.

4. IMAP provides a more convenient, stable, and reliable user experience, and two-way communication with the client through WebMail can avoid email loss.

   POP3 is more likely to lose emails, and cannot download the same email multiple times (many current POP3 email servers already support retaining original emails and multiple downloads).

5. IMAP provides access to emails from multiple devices (such as mobile phones, computers, tablets, etc.), making it easy to check emails anytime, anywhere.

6. The summary browsing function provided by IMAP is convenient for viewing the arrival time, subject, sender, size and other information of the mail, and then decide whether to download and open it.

The third step, the mailbox will be added successfully at this time, but the following security warning will pop up

 Step 4. The reason for the above warning is that the server configured by default is the server of the web version, the server of the client adopts SSL encryption, and the server address is different from that of the web version.

Step 5: Go to the NetEase corporate mailbox to check the parameters configured on the Outlook client.

POP, SMTP, and IMAP server address settings for corporate mailboxes. (including overseas client configuration) (163.com)

The query results are as follows:

Step 6: Open the server settings, the original setting is the wrong web email address. Addresses that need to be changed to IMAP and SMTP.

 

 The sixth step is to change the server and port according to the query results. To change the incoming mail to IMAP and the outgoing mail to SMTP.

 

The seventh step is to close Outlook and reopen it. The reason for the problem is that the client accesses the server of the web version, which causes the SSL authentication to fail. The client should use the client's protocol to access the right server.
