Security warning when you start Outlook 2007 and then connect to a mailbox that is hosted on a server that is running Exchange Server 2007 or Exchange Server 2010: “The name of the security certificate is invalid or does not match the name of the site”
I ran into an issue where I had imported a SAN certificate into my exchange organization. Once I had imported it I started to get outlook SSL warnings. The issue was that the internal URLs for many of the services outlook connects to were setup with my internal server domain IE host.internaldomain.com. Now I was faced with an issue where I could not get another SAN cert to encompass the host names of my internal domain, because the Domain admin previous to me named the internal domain of a legitimate domain and we did not own that domain. ie internal domain is contoso.com or yahoo.com these domains are owned by someone else thus no SAN cert will be issued. The way around this was I changed the internal URL entries for multiple virtual directories, and created a DNS look-up zone. I found A KB article that shows how to do this.
Mail contacts or mailboxes now showing up in GAL
I came a cross an issue where mail contacts and some mailboxes where not showing up in the Global Address List. The funny thing was they showed up in in Outlook Web Access (OWA). The reason this was happening was our outlook clients were running in cached mode and were using the Offline Address Book for GAL look ups (OAB). All I had to do was just update the OAB on the exchange server and hit send and receive from the client machine.
The command you use is below Use the Exhange Management Shell (EMS) to do these
To Update a particular OAB use the below command
Update-OfflineAddressBook “Name of Address Book”
To update all OABs use the belwo command
Get-OfflineAddressBook | Update-OfflineAddressBook
