Outlook error 0x800CCC7D

The organization I am associated with has provided me with housing and access to their non-secure wireless internet. I am able to use the internet access and receive email using Outlook 2003, but when I try to send I am getting the error message: "Task 'Gmail - Steve - Sending' reported error (0x800CCC7D) : 'Your outgoing (SMTP) server does not support SSL-secured connections. If SSL-secured connections have worked in the past, contact your server administrator or Internet service provider (ISP).'"

The organization is running Microsoft Exchange Server 2000 and uses Outlook 2003 with that server. However, the wireless access I am using is outside their firewall. If I take my computer to a different location and use other wireless access I have not problem with my current settings.

I've checked with the organization's network administrator and he is not sure how to remedy the issue.

It's another indication that the network in question is blocking certain kinds of traffic.  TRACERT is sometimes blocked for security reasons.  A hacker can use TRACERT to map out the devices between two points, helping them decide how to attack a network.  The fact that TRACERT isn't working is more evidence that the network is blocking some types of traffic, which tends to contradict the network admin's assertion that this network is "open".  Try performing a TRACERT from another network and I'll bet it works.

Sounds like you're using RPC/HTTP and according to Microsoft, it sounds like your server doesn't support it.

Thanks, dexIT. I might be in over my head, but I don't think this is the issue. I have not been using Outlook with an exchange server - just for retrieving POP3 accounts via internet. I am not trying to access the organizations exchange server, just to use their open wireless access to access my Gmail using Gmail's pop and smtp servers. As I mentioned, it works on other private and public wireless accesses, just not on this one.

Simplify Active Directory Administration

Administration of Active Directory does not have to be hard.  Too often what should be a simple task is made more difficult than it needs to be.The solution?  Hyena from SystemTools Software.  With ease-of-use as well as powerful importing and bulk updating capabilities.

then you need to check if your pop3 port is open on their firewall

or you need to check to see if their ISP will allow you to use the default port 110, although rare, you sometimes may need to change the port on specific ISPs.

I checked with network admnistrator. He says that the internet access I am using through their open wireless access is totally outside of their firewall, so there should not be an issue of ports being blocked

Hi, skbx2.

Since the settings work fine when you connect via another wireless network the problem must be with this one network.  I understand that the network admin doesn't think that there should be an issue, the evidence at hand suggests that there is.  Has the admin actually checked to see if there are ports being blocked?  If not, then they should.  

Here are some other things I'd try.

1.  Use Tracert to see the path your request are taking.  I'd test both by IP and by host name.  Note down the hops.

2.  Use Telnet to attempt to connect to the SSL port at each hop.  I believe you'll get an error message if the device representing a particular hop is blocking traffic.

Thanks BlueDevelFan for your response. I tried using Tracert, but for some reason I get "Request Timed Out" for all 30 attempts. I am getting this response even on web addresses that are working fine in Internet Explorer. I tried smtp.gmail.com (where I am having trouble receiving) and pop.gmail.com (where I have no problems. In both cases I just get the Request Timed Out response. I tried extending the time, but that made no difference.

You tried this via the connection that you're having problems with or via a connection that is working?

I tried via the wireless access point that has been giving me problems. However, it has only given me problems so far in two areas:
1. Sending Gmail (no problem receiving)
2. Downloading and installing Windows updates

Then that connection must be blocking some kinds of traffic.  Try doing a TRACERT to www.google.com.  What happens?

I tried www.google.com and got the same result - "request time out." No problem navigating to google, so I don't know why tracert won't find it.

I will be checking the computer on a different wireless network today to see if the Tracert program will work from there. Then I will get back with my network admin and advise of status. Thankis for keeping this active.

No problem.

The recent posts have been very helpful in identifying the source of the problem. However, the organization with the network has a network structure that is really beyond the "know how" of the network administrator. So, without more specific suggestions as to what might need to be done within their network or firewall, I think I'm stuck on this one. I really do appreciate your help and patience as we've tried to work through this.

It did not complete solve my issue - but mainly because my network administrator is not well enough verse in our system to follow through
