Outlook 2003 Can Not Connect To SSL Servers

Hello;

I am running Outlook 2003 on top of Vista Home Premium with Windows Live One Care for security.

Over last year, AT&T (ex SBC)/Yahoo directed all of their users to change port settings on e-mail servers to SSL connections (ports 995 and 465). For last few months no problems, then I began receiving error "0x800CCC7D" and could no longer connect to outgoing SMTP server; according to MS article kb/289967 this is allegedly an error on server side.

After extended discussion with AT&T tech support, they advise that there is no general fault on their server; their Tier 2 ran diagnostic on their end and confirmed that server can accept outgoing e-mails from my account. They also confirmed all of my client settings are correct (as indeed they have worked fine in past). They claim it is client issue.

With some advise on broadband discussion boards I have attempted following:

1) turned off both Firewall and e-mail scanning in One Care;
2) booted in Safe Mode with Networking
3) bypassed router with direct connection to modem (I am using DSL service)
4) launched "detect and repair"

None have worked. As a temporary fix, I have reset ports to prior non-SSL server, but this has triggered stream of warnings from AT&T that I am not allowed to keep using these servers and they will soon be disconnected.

Can anyone provide any insight as to why client is suddenly unable to connect via SSL?

Unless anyone can suggest other alternatives, my next step is to uninstall and reinstall Outlook client. I have several GBs of e-mail in various *.pst folders, as well as contacts, etc. Can anyone point me to comprehensive step by step plan for doing so that will not risk my data?

Is it possible to uninstall just Outlook and reinstall without disturbing entire MS Suite, or is better to do global reinstall?

Thanks for your interest,

RF
