The server you are connected to is using a security certificate that cannot be verified..The target principal name is incorrect....Do you want to continue using this server?

Brand new computer running windows 7 64bit, outlook and office 2007 installed, initial problems with temporary user profiles, followed advice and removed user profiles from system registry and all seemed to be fine. Computer been running for about one week with two user profiles and now I am suddenly getting an error message when I start up Outlook and occassionally when browsing the internet, it reads:

The server you are connected to is using a security certificate that cannot be verified..The target principal name is incorrect....Do you want to continue using this server? (If i hit yes I can then send emails)

When I open view certificate it says: This CA Root certificate is not trusted. To enable trust, install this certificate in the Trusted Root Certification Authorities store. (Issued to and by: Cisco Appliance Demo Certificate - valid from 2/10/2009 to 3/10/2019).

Problem is I don't know what the certificate is, what I need it for, how to locate it, how to move it etc  I have read some forums but they start getting too technical. I need easy step by step help.

I tried uninstalling outlook 2007 and reloading and clearing ssl states in internet options and reseting to default (as suggested by someone) but it made no difference.

Problem is when you leave the store with new computer nobody wants to know you if you need help!

Can anybody please help? THANKS

Hi,

Welcome.

Just one advice, never download and install anything in your PC unless you know and trust it.

 >"Brand new computer...I need easy step by step help."

Contact the PC maker support team insistently.

>"...office 2007 installed...

Support at: http://answers.microsoft.com/en-us/office/default.aspx#tab=1 and ask your Outlook question there.

You can also check if this issue happens when using Windows Live Mail that can be downloaded at: http://download.live.com/wlmail.

>"The server you are connected to is using a security certificate that cannot be verified..."

Just to know more about server certification at: http://en.wikipedia.org/wiki/Certificate_server .

Remember: Keep system and security tools updated .

Success.

Rgds.

In my case I had to remap the incoming mail server from pop.gmail.com to imap.gmail.com becasue the certificate originated from imap.gmail.com

if you are using yahoo mail or sbcglobal mail Try changing your incoming mail server to pop.att.yahoo.com

"...the server you are connected to is using a security certificate google..."

 

None of these solutions worked for me below. I'm using Office Outlook 2007.

 

Solution is to use imap for your incoming mail server and setting the incoming mail server to imap.gmail.com

http://support.google.com/mail/bin/answer.py?hl=en&answer=82350

Solution: Make sure you've set up your mail client for IMAP1 access rather than POP2 access. In addition, please verify that you have entered 'imap.gmail.com' rather than 'pop.gmail.com' as your Incoming Server setting.

Hi,

@ machocloud

@ bj and family

I was getting same error for outlook 2010 in win 8 RP for yahoo imap. My incoming email configuration was imap-ssl.mail.yahoo.com, while my certificate address was *imap.mail.yahoo.com. I also changed the incoming email configuration to imap.mail.yahoo.com, and the problem is so far resolved.

 

But personally speaking, I have faced issued with this incoming mail configuration in past (my yahoo mail used to stop). Not the case now. So, not sure what happens now. I just applied this corrective action now.

The web-hosting company that provides our email services has very detailed instructions that were no help at all...

We have multiple domains and the instructions were to Use your "Primary Domain" as the imap and smtp server like: imap.yourprimarydomain.com and smtp.yourprimarydomain.com for each email account.
example: I did not like seeing emails sent out From *** Email address is removed for privacy *** using smtp.tempuri.com.

After reading the help tips here. I looked closer at the pop-up warning: 
"The server you are connected to is using a security certificate that cannot be verified..The target principal name is incorrect....Do you want to continue using this server?"
There was a clickable link that allowed me to see the details and the certificate was issued to my service provider not to my primary domain. 

So, Outlook 2010>File>Account Settings Box "CLick Box>Rectangle Account settings Pop-up>
changed every email account to use imap.hostcentric.com and smtp.hostcentric.com.

Everything Works Great Thanks to this Thread!!!
