Outlook is unable to connect to the proxy server.(Error Code 10)

Hi,
I had problems with RPC proxy, I was trying to setup cutover migration.
So I read somewhere that i need to change the certprincipalname with Set-Outlookprovider.
But after this change my outlook was not working anymore
The settings before the change were:
Name Server CertPrincipalName TTL
EXCH
1
EXPR
1
WEB
1
So I set this back to the original (above) but this didn't helped...
Outlook 2013 and Exchange 2013
There is a problem with the proxy server's security certificate. The name on the security certificate is invalid or does not match the name of the target site mail.abc-company.com.
Outlook is unable to connect to the proxy server.(Error Code 10)

Hi,
Please make sure the mail.abc-company.com is included in your Exchange certificate which has been assigned with IIS service.
If possible, please run the following command for double check:
Get-ExchangeCertificate | FL
For Autodiscover service, please run
Test E-mail AutoConfiguration to check if the connection is successful in Log tab and confirm the other services URL can use proper namespace in Results tab for request access.
If the Autodiscover service fails, please create a SRV record with mail.abc-company.com for Autodiscover service to have a try:

Intermittent proxy error "There is a problem with the proxy server's security certificate. Outlook is unable to connect to the proxy server "

Hi all,
From time to time (at least once a day), the following message pops up on the user's screen:
"There is a problem with the proxy server's security certificate. Outlook is unable to connect to the proxy server . Error Code 80000000)."
If we click "OK" it goes away and everything continues to work although sometimes Outlook disconnects. It is quite annoying...
Any ideas?
Thank you in advance

Hi,
For the security alert issue, I'd like to recommend you check the name in the alert windows, and confirm if the name is in your certificate.
Additionally, to narrow down the cause, when the Outlook client cannot connect again, I recommand you firstly check the connectivity by using Test E-mail AutoConfiguration. For more information, you can refe to the following article:

Outlook is unable to connect to the proxy server. (Error code 0)

Hello,
I have just commenced a Exchange 2007 SP3 to Exchange 2013 SP1 migration following the following guide: http://blogs.technet.com/b/meamcs/archive/2013/07/25/part-1-step-by-step-exchange-2007-to-2013-migration.aspx
As per the above guide, my 2007 environment is now known as legacy.company.com and my 2013, webmail.company.com.
I'm using the same certificate on both boxes and it has the names autodiscover.company.com, webmail.company.com and legacy.company.com. All that seems to be working fine.
OWA is functioning perfectly, hitting https://webmail.company.com will pass the user off to https://legacy.company.com if the mailbox is on 2007. Alongside this, Outlook also has no issues connecting to 2007 mailboxes with the client proxy settings
being reconfigured to https://legacy.company.com automatically.
My problem comes when a mailbox is migrated to 2013. OWA functions fine and presents the mailbox but Outlook is unable to connect, presenting the error:
There is a problem with the proxy server's security certificate.
The name on the security certificate is invalid or does not match the name of the target site webmail.company.com.
Outlook is unable to connect to the proxy server. (Error Code 0)
If I modify the Outlook client's settings and disable "Only connect to proxy servers that have this principal name in their certificate: msstd:webmail.company.com", Outlook connects and functions fine.
I'm at a loss and have tried everything I can think and find on google. Any suggestions would be greatly appreciated.

Hi,
Please refer to the following article :
http://support.microsoft.com/kb/923575
Cause:
This issue may occur if one or more of the following conditions are true:
The connection to the server requires a certification authority (CA).
You have not trusted the certification authority at the root.
The certificate may be invalid or revoked.
The certificate does not match the name of the site.
A third-party add-in is preventing access.
Solution:
To examine the certificate, follow these steps:
In Microsoft Internet Explorer, connect to the RPC server or to the secure server. For example, type
https://www.<var>server_name</var>.com/rpc in the Address bar of the Web browser, and then press ENTER.
Note The <var>server_name</var> placeholder references the RPC server name or the secure server name.
Double-click the padlock icon that is located in the lower-right corner of the Web browser.
Click the Details tab.
Note the information in the following fields:
Valid to
The Valid to field indicates the date until which the certificate is valid.
Subject
The data in the Subject field should match the site name.
Hope this helps!
Thanks.

Please help me, thanks.

Hi,
i think this has to do with the "Document Conversions Load Balancer Service".
If you don't need the service than try to stop it:
Start Central Administration > Operations > Services and stop the service.
or
If you need it the service, try this:
Start Central Administration > Operations > Service Account
Change the service account to "Document Conversions Load Balancer Service" And Select a "Network Services" Click Save
Hope this helps!

Community Publishing-"Unable to connect to the CPS server" Error

I am trying to connect to Community publishing.
I download the Community Publishing Air app, but when I put in my username/password,
I get this error "Unable to connect to the CPS server. Please make sure your firewall settings allow access to this url:

I have updated Air, but got the same behavior.
I am running osx (10.6.6) on a 8 core Xeon.
Any suggestions?
Thanks

Hi Clay,
Do you have a firewall, or are you behind a corporate firewall that blocks certain ports on your machine?
What do you see when you visit this URL?
http://cps.corp.adobe.com
How about the following URL?

"Safari can't connect to the proxy server"

Hello again...
My 10.6 Server is up and running! thanks for all the help...however...
When I try to access the internet via Safari from the actual server, I get the "Safari can't connect to the proxy server" message" but all the client machines can successfully access the internet....
I'll start to read up on proxies but if someone can offer a suggestion in the meantime, that would be terrific. I know it's something simple I am missing...
thanks!

No snarkiness taken Mr. Hoffman...As a full-time high school teacher, I've been setting up our small school server on my own time for the past three months...with the help of the server docs, manuals, and the great help found within this forum, we are finally to a point where we can begin using the server.
What I'm just not understanding is WHAT proxy do I use? I see all kinds of proxy servers out there but is there a specific one I should be using?
Again, forgive me for my ignorance on this matter...I just don't understand why after a year of not using a proxy server, all of a sudden we need to have one? And this issue came about when Safari was unable to "connect to the proxy server"...
MrHoffman wrote:
1) So normally, there ISN'T a proxy being used?
Proxies are used in school and corporate environments, and as a mechanism to >implement "network nanny" or parental controls, or when information leakage >involving sensitive or classified data, or personal or credit card data, or >other sensitive data is involved.
When IT folks (or parents) are looking to monitor or control or track network access.
up to this point I don't believe we were using a proxy server?
2) A proxy "regulates" what traffic is passed between machines?
A proxy can enforce access, or can cache access, yes.
So no proxy in effect means traffic goes unchecked between computers...?
Correct.
do we HAVE to use a proxy server with the server?
3) Where does a proxy take effect? At the Router/Gateway? The Server? or >individual machines?
A functional proxy requires a proxy server, and settings at the firewall, and >on the client box.
The proxy setting can be established via WGM, or locally via the system >preferences, or (and the following are less common) via malware or such, or due >to a bug. These settings are usually altered with WGM and system preferences, >in the vast majority of cases.
Enabling a proxy server on the snow leopard server should help us out...but again, which address do I use? (in the server doc you referenced, it had "proxyserver.apple.com:8080")but I think that was just the format to use...
Without intending any snark, read the manuals? Servers are big and complex >and expect an understanding of much more than the client boxes do; that's the >inherent difference between "server computing" and "client computing", after >all.
I'm definitely appreciating how much involvement and understanding it takes to get one of these set up...and over the past three months, we've come a long way...
again, thanks for the guidance and help!

Possible workaround for: Launch Debugger Error "Unable to connect to the RDS server"

I do not yet have a reproducible case for this. *Sometimes* ColdFusion Builder throws the "Unable to connect to the RDS server" error, when attempting to start a debug session against a remote server. However, "RDS Dataview" and "RDS Fileview" views correctly list the servers and their related data/file, and testing RDS connection result is "Test connection was successful". The workaround is:
1. Login to the ColdFusion Administrator
2. Navigate to "Debugger Settings" page (beneath "Debugging & Logging")
3. Click on "Stop Debugger Server" -or- "Restart Debugger Server"
4. Restart ColdFusion Application Server
Notes:
a) Step #3 must be done via ColdFusion Administrator, not via ColdFusion Admin API (stopLineDebugger()|restartLineDebugger())
b) Step #4 can be done via ColdFusion Administrator -or- ColdFusion Builder
c) Note that there is a CF9 Release Note for Bug #78488: "When a server having "Windows service option" ENABLED is added as a remote server, then Start-Stop-Restart operation cannot be done on it." However, I've found that "Restarting" a remote server, that is running as a Windows service, is possible in ColdFusion Builder (at least this is so on standalone developer edition). Like Bug #78488 says, I am unable to "Stop|Start" a remote server that is running as a Windows service. I'm just mentioning all of this, due to my suggestion in "b", that CF can also be restarted via ColdFusion Builder.
It is interesting that attempts to stop|restart the debugger server, via CF Admin API, do not resolve the issue. So, it seems that the "Stop Debugger Server" and "Restart Debugger Server" buttons, in CF Admin, are doing more than calling the corresponding CF Admin API methods.
Attached is an image of the error.
Just posting all of this as an FYI, in case it helps anyone.
Thanks!,
-Aaron Neff
(OH.. I'm unable to attach images at this time *DOH!* ..well, I'll try to remember to update this post w/ the image, once I see that attachments are allowed.)
I'll try to describe the error message window:
- It is 494x452 pixels
- Title of the window is "Error occurred while launching the Debugger"
- Body content of the window is as follows:
Unable to connect to the RDS server 'ServerNameHere'
Ensure that the server is currently running and that line debugging and RDS are enabled. You may also need to check your RDS connection settings in Eclipse to ensure that they are correct.
Error Message:
-1:Error connecting to JVM for debugging at localhost:5005. Could not attach to the VM at port 5005. You must specify this debugger port in the JVM settings of your application server, for example: -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5005. You will also need to make sure that another debugger is not currently connected to the CF JVM at the same port (5005).

[DataSource.Error] OData: Request failed (ConnectFailure): Unable to connect to the remote server
Stephen

OData is a web service and so long as you can access it from your current network context, it'll work. Home, Internet Café, Hotel, Airplane -- doesn't matter. If the data source is private and is on a restricted network (like some sort of private data analysis
source internal to your company), then you will need to VPN into that network before you attempt to refresh your data.
I have noted some basic steps in my blog that might help you setup the basics and verify with a known publically available OData source.
