Hi All, Can you please provide some information on how to solve this problem I have. Internal issue only. Exchange 2010 Outlook 2010 We use to have domain1.com. This was working fine with purchased SSL cert. We then had a company merger and now we have domain2.com as our default domain. No problem. New cert, updated all the links (owa, control panel, auto discover), but we have an issue. When loading Outlook, I get two security popups about connecting to domain1.com. If you check the certificate, it's the certificate of domain2.com. I think it's a DNS issue of some kind. We removed domain1.com from internal DNS and then Outlook clients could not connect at all. Any ideas on what to check?

Make sure all your virtual directory URLs specify domain2.com.Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

Are you talking about through EMC? They are all set correctly.

I don't know. I don't use EMC for this sort of thing. See Set-ClientAccessServer -AutoDiscoverServiceExternalUri. Check Set-OutlookAnywhere -ExternalHostName. Also see the -ExternalUrl and -InternalUrl properties of Set-OwaVirtualDirecotry, Set-WebServicesVirtualDirectory, Set-AutodiscoverVirtualDirectory, Set-ActiveSyncVirtualDirectory, Set-EcpVirtualDirectory, and Set-OabVirtualDirectory.

Thanks, I've looked at this and it looks good except Set-AutodiscoverVirtualDirectory. There is no internal url specified. Also, what's the best way to show the urls. For example, a get-ClientAccessServer will not show the current urls. Thanks

What's important in Get-ClientAccessServer is the AutoDiscoverServiceExternalUri property.Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

Hi infused, Does your Outlook in domain1 or domain2? If you recreate a Outlook profile manually, will this issue occur or not? Thanks, Evan
