certificate errors! Thankfully, it's pretty easy to fix. Struggling with a difficult Exchange 2010 or Exchange 2013 migration? We've learned the hard lessons so you don't https://support.microsoft.com/en-us/kb/2006728 have to! Contact us to get your Exchange upgraded and online. Let's assume your Exchange server is known as "exch-1.domain.local" internally but as "mail.domain.com" externally. Solution If you haven't already, you need to add your public zone ("domain.com" in this example) to your internal IP and setup a record to point "mail.domain.com" to https://www.puryear-it.com/fixing-certificate-errors-in-outlook-for-exchange-2010 the same IP as "exch-1.domain.local". I like using CNAMEs for this so you don't have to update 2 records should it ever become necessary. Like a lot of Exchange 2010 howtos, this one uses the Exchange Management Shell on your Exchange 2010 server. I'm a big fan of backing up settings before changing them so run a few "get" commands first: > Get-WebServicesVirtualDirectory | Select InternalUrl,BasicAuthenticationExternalUrl,Identity | Format-List InternalUrl : https://exch-1.domain.local/EWS/Exchange.asmx BasicAuthentication : False ExternalUrl : https://mail.domain.com/ews/exchange.asmx Identity : EXCH-1EWS (Default Web Site) > Get-OabVirtualDirectory | Select InternalURL,ExternalURL,Identity | FL InternalUrl : http://exch-1.domain.local/OAB ExternalUrl : https://mail.domain.com/OAB Identity : EXCH-1OAB (Default Web Site) > Get-ActiveSyncVirtualDirectory | Select InternalUrl,ExternalUrl,Identity | fl InternalUrl : https://exch-1.domain.local/Microsoft-Server-ActiveSync ExternalUrl : https://mail.domain.com/Microsoft-Server-ActiveSync Identity : EXCH-1Microsoft-Server-ActiveSync (Default Web Site) Once you have all that info backed up somewhere safe (just copy it to Notepad and save the file), you can start fixing things: > Set-WebServicesVirtualDirectory -Identity "EXCH-1EWS (Default Web Site)" -InternalURL https://mail.d

The exchange server has a wildcard SSL certificate installed *.domain.com, (for use with autodiscover.domain.com and mail.domain.com). The local fqdn of the Exchange server is exch.domain.local. With 2010 certificate error this configuration there is no problem. Now I started upgrading all Outlook 2003 to Outlook 2013, and I start to get consistently a certificate error in Outlook : The Name on the security certificate is invalid or does not match the name of the site I understand why I get that error: Outlook 2013 is connecting to exch.domain.local while the certificate is for *.domain.com. I was ready to buy a SAN (Subject Alternate Names) Certificate, that contains the three domains exch.domain.local, mail.domain.com, autodiscover.domain.com.
