Hi Tran_Hoa_Binh,
As I can see from the screenshot which you've shared, it seems that:
- It might be an IMAP server configuration issue
- Try to reset your password
- Switch the IMAP configuration to SSL (From port 143 to 993) if it's not secure.
- Check your Windows Firewall, modify inbound rules, and add the port to "Allow the connection"
- Contact your service provider, if they did any changes on the mail server, they need to provide a new configuration.
