Outlook Certificate Error Exchange 2013
a way (setting, workaround, registry key etc.)to force Outlook 2010 to ignore the fact that Exchange is using a self-signed certificate andJUST CONNECT without being so squeamish and annoying about the outlook is unable to connect to the proxy server Certification Authority that is not trusted and blah blah blah? Before you answer: unfortunately no, I cannot force/convince the administrator to purchase and install a trusted CA's certificate nor make him install an internal CA. Thank you.

Open outlook 2013 certificate error it and save to file and then import that file. That pre-supposes that the cert is indeed a plain Exchange cert and unrelated to the CA, if there was one. Your next problem could well be the cert name not matching. You’re pretty much on your own then. "Paolone67" wrote in message news:df4c989c-d905-45e1-a45d-f61b5acc5603...

Outlook 2010 should always warn if using a self-signed cert.

Outlook Security Certificate Cannot Be Verified
External (Outlook Anywhere) clients are getting certificate error with a public certificate Posted on 2015-01-26 Exchange Outlook SSL / HTTPS 1 Verified Solution 16 Comments 358 Views Last Modified: 2015-02-01 Hi guys, This weekend, I changed out a https://social.technet.microsoft.com/Forums/exchange/en-US/df4c989c-d905-45e1-a45d-f61b5acc5603/ignore-outlook-anywhere-selfsigned-certificate-error?forum=exchangesvrclientslegacy certificate in Exchange. I got a public cert and used all the proper subject alternative names. However, the former cert, installed before my time, was a wildcard and I am not a proponent of a wildcard cert in Exchange. I got a standard UCC cert and gave the common name 'mail.mydomain.com'. Everything went well and the change was transparent for the most part. However, the Outlook Anywhere clients in my China office are experiencing the following error https://www.experts-exchange.com/questions/28603907/External-Outlook-Anywhere-clients-are-getting-certificate-error-with-a-public-certificate.html when trying to open Outlook (keep in mind that if they VPN in and open Outlook or simply go to webmail.mydomain.com or mail.mydomain.com/owa externally they have no issues): "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 site. Outlook is unable to connect to this proxy server." To me, this means there may be a manual certificate installed on these external boxes for some reason? The configuration of their Outlook anywhere setting is 'webmail.mydomain.com' as the server to connect to. However, the public certificate works (i.e. there are no certificate errors either internally or externally when attempting to connect via webmail.mydomain.com) with no issues. As usual, any help is greatly appreciated. Thanks! -Roy 0 Question by:roycbene Facebook Twitter LinkedIn Google LVL 7 Best Solution bySatyendra Sharma Ok so in your case since you are not using wild card you would have to set the certprincipalname to $null that way whatever url you have specified in the Outlook Anywhere configuration will be used i.e. Go to Solution 16 Comments LVL 7 Overall: Level 7 Exchange 6 Outlook 2 Message Expert Comment by:Satyendra Sharma2015-01-26 Is that the only office affected with this problem?

Assigned services, reconfigured all URL's for external and internal access to certificate is invalid be identical (previous cert was a SAN cert with .local domain names and since they are no longer available we are having to change this), setup split DNS so internal and external clients all use the same DNS name for access. Everything works as expected, with the exception of Outlook clients receiving a mismatch certificate error... it appears the server is presenting the server.domain.local FQDN to the client and with the SSL being *.domain.com it doesn't match... I have followed all guides/articles I found ensuring that all URL's are setup properly and all point to the same external DNS name. Autodiscover internally also works and passes (we do not have it setup to autodiscover externally but Outlook anywhere does function as it should when manually configured, this has been tested) What has me perplexed with this issue is that newly created profiles/accounts do not have this issue so it seems to be more of an Outlook profile issue rather than a server issue. I can open Outlook and use my previously configured profile and I get the SSL mismatch error..
