I’ve been using CyberPanel for a few months now and I’ve learned a lot from DOCS and COMMUNITY and solved some of my problems.

At the moment, I have some outstanding questions, such as:
Outlook 2003/2007/2010, I can’t use SSL
Outlook Tip: The specified server has been found, but the server is not responding.Please check if the port and SSL information are correct.

I realized that maybe my Outlook version was too old because now Thunderbird and Webmail are working fine.

So, what should I do in this situation?

There are also a lot of people around me who use Outlook 2010 or even Outlook 2007/2003, and I hope to find a way to work even in the old Outlook.

Here’s how I do it:
Fresh install of cyberpanel and make sure that both Thunderbird and Webmail are working properly.
Tried on Outlook 2010 or Outlook 2007/2003, POP3 port 995, SMTP port 465 and it doesn’t work.

Then I enabled TLS v1.1 in LiteSpeed WebAdmin Console/Listener SSL > SSL and Outlook didn’t work as well.

Then I modified 10-ssl.conf as root:
#ssl_min_protocol = TLSv1.1
Outlook doesn’t work as well.

Is my operation or operation process incorrect?

Thank you!

Why do you want to keep using Outlook 2007 ? As per microsoft site Office 2007 is now retired

want to know few things which port you are trying and is 2007 offer with SSL connection or not?

There are probably hundreds of thousands of people in this country who are still using outdated versions of Office 2003/2007/2010, which also includes many businesses.
So, this may be something that no one else can understand.

POP3 port: 995
SMTP port: 465

As I understand it, Office 2007 offers TLS v1.1

Can someone who is enthusiastic provide some configuration advice?

Thank you so much!
