The fundamental goal is to move the user mail boxes and settings with very little disruption. Migrating Exchange 2003 to Hosted Exchange migrating our internal exchange to hosted IN THIS DISCUSSION Join the Community! Creating your account only takes a few minutes. Join Now We've recently built an Exchange 2010 server and at the same time have been upgrading our workstations to Win7 with Office 2010. The new Exchange. 2010 server also hosts OWA and we have a Verisign certificate for our external webmail address. As I migrate users from the old Exchange 2003 server to the 2010 server, they're getting certificate errors that the server name doesn't match the certificate. The Verisign cert is for webmail.xxx.com. The Outlook 2010 users get 3 cert errors, one for exm02 (the netbios name) another for the FQDN, and one for mail.xxxx.com. For $800 per name I can add these to the Verisign cert, but trying to avoid that. I set up an internal CA, and issued a cert to the new Exchange server, but Outlook users are STILL getting the certificate errors. Outlook still sees the verisign cert, but doesn't seem to care about the cert issued from my internal CA. My CA is a trusted authority on the workstations per group policy. I'm new to certs and CA's and even Exchange 2010 so I have no idea what I'm doing wrong here. Can anyone help?
