The process is simple: we’ll take a look at each of the listed solutions and explain the process involved.
Check the email server configuration
As per the error message, the issue appears to be with server configurations. In this case, check email server configurations as follows:
The incoming email server address is usually in the format of mail.contoso.com or imap.google.com. You can get this information from your ISP or administrator. For many email accounts, you can find this information in the POP and IMAP server name reference provided by Microsoft.
Make sure you have the outgoing email server information from your ISP or administrator. The outgoing email server address is usually in the format of mail.contoso.com or smtp.contoso.com.
The servers are configured to use the server’s name (mail.contoso.com) followed by a colon (:) and then the port number followed by another colon and then another number (usually 1). If the server’s name is valid, you only need to change the number between the two colons.
POP3 and IMAP servers use different ports for incoming and outgoing emails. Contact your email provider to determine the ports they support for POP3/IMAP and SMTP. If you’re connecting to a Microsoft Exchange server, your organization’s Exchange server administrator can provide you with this information.
If you started experiencing this sync issue after you recently installed a Windows update, you can uninstall the update.
Perform System Restore
If you’re still having trouble despite trying all of the above, you can try doing a system restore to a point before you started encountering the issue.
