got fixed but now your internal Outlook users are getting certificate errors! Thankfully, it's pretty easy to fix. Struggling with a difficult Exchange exchange 2013 certificate error internal server name 2010 or Exchange 2013 migration? We've learned the hard lessons so you don't 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 outlook security alert certificate keeps popping up add your public zone ("domain.com" in this example) to your internal IP and setup a record to point "mail.domain.com" to 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.do
