To accommodate http://serverfault.com/questions/627870/outlook-security-alert-the-name-on-the-security-certificate-is-invalid-or-does email, we have 3 Exchange accounts per user to manage this. All users use their CompanyA account to log into the domain. CORP\user user@companyA.com CORP\user-companyb user@companyB.com <-- only used for email CORP\user-companyc user@companyC.com <-- only used for email Email works fine internally and via OWA. The problem exist when setting up Outlook for remote users who need access to companyB and companyC emails, Outlook pops up the certificate error. The SSL cert SAN has the following DNS names: webmail.companyA.com www.webmail.companyA.com CORP-SBS CORP-SBS.local autdiscover.companyA.com I was told by the users who access companyC email address remotely that this never used to happen before. This started with the CEO changed DNS providers on his own and in the process the original DNS settings were lost. He mentioned something about an SRV record being created which corrected this issue but that's about it. Looking for guidance on how to properly address this. ssl exchange outlook certificate share|improve this question edited Feb 15 '15 at 4:28 HopelessN00b 44.5k1798168 asked Sep 11 '14 at 15:37 Mike66350216 1291111 add a comment| 2 Answers 2 active oldest votes up vote 23 down vote accep
Warning" dialog box with the message; The server you are connected to is using a security certificate that cannot be verified. The target principal name is incorrect. I clicked on "View Certificate" and installed the certificate, but I still get this https://www.msoutlook.info/question/613 dialog each time I start Outlook. Clicking "Yes" each time allows me to use Outlook as normal but how can get rid of this dialog? Usually you get this error when you are using a shared hosting http://www.slipstick.com/outlook/security-warnings-in-outlook/ account with your own domain and connect via SSL. Another common cause is that your ISP has changed the name of their mail server and is redirecting you from the old server name to the new certificate error one and the name of the old server isn’t on their new SSL certificate. Looking at the certificate usually provides the answer. Name on the certificate should match the name of the mail server The solution is quite simple; click on the “View Certificate…” button and look at the “Issued to” name. This is usually the name that you’ll need to specify for your incoming and/or outgoing server in your account configuration. In some the name on cases, this still won’t work when the certificate holds multiple names. You can then select the “Details” tab and see if the certificate holds a field called “Subject Alternative Name”. If so, then you’ll find other names that you could try behind the “DNS Name=” value. If none of those names work either, contact your ISP and ask for the correct name of the mail server that you should use. Another (less secure) alternative would be to disable the use of SSL for your mail account. No need to install the certificate As long as the name on the certificate doesn’t match the name specified in your account settings, you’ll get this warning message. Installing the certificate will not help in any way and isn’t needed either. The only case in which installing the certificate is needed, is when the names do match and the certificate isn’t issued (trusted) by a Certificate Authority. These are so called “Self-Signed Certificates”. In that case, only install the certificate if you trust the domain that is specified on the certificate and if the administrator responsible for that domain has instructed you to do so. Background information Many shared hosting solutions or ISPs are now offering secure access to your mailbox via Secure Sockets Layer (SSL). In order to make an SSL
SystemsHome / Outlook / Security Certificate Warning in Microsoft Outlook Last reviewed on March 22, 2016 —8 Comments This hard to understand error means the security certificate your email server is using has expired or is invalid for other reasons. I'm getting a security warning when I open Outlook. It says: 'The server you connected to is using a security certificate that cannot be verified. A required certificate is not within its validity period when verifying against the current system clock or the timestamp in the file' That message is saying that the certificate the mail server uses has likely expired. If you are the administrator, you need to install an updated certificate; if you are an end-user, you need to speak to your admin. You can't hide the warning or turn it off, but in all likelihood, it's safe to OK it and connect to your mail server. The message made perfect sense to me but not to the people who asked about it, so I asked a couple of family members who aren't into technology what they thought the message was trying to tell them and what they would do if it came up while they were on the computer. Their answer: it "hurt" to read it and they'd ask me to look at it. I guess that proves it's a poorly written, overly technical error message. Target Principle name is incorrect I have a SSL IMAP email account that I just setup in Outlook. Every time I run the program I get a popup: "Internet Security Warning" The server you are connected to is using a security certificate that cannot be verified. The target principle name is incorrect. View Certificate. The certificate is self signed so I always just click Yes to continue using the server/email account, but how do I get Outlook to remember? This warning indicates the server name does not match the name in your account settings, or in the case of Exchange server, that the address in the autodiscover file does not match the address the server is using. This is a common problem when the administrator uses self-published certificates. If you can't change the server name you use in Outlook, you can publish the certificate in the Certificate store to reduce the frequency of the alert. In the Trusted Publishers folder should suffice or use the automatic setting. This probably won't totally eliminate the dialog, but you'll see it less often, usually only when you restart Outlook. To publish the certificate, click View Certificate then Install Certificate. Choose Current user, click Nest then Install. For example, in the dialog in this screenshot, the server certificate was issued to pop.secureserver.net
