Exchange 2007 local send /recieve

I have a new SBS 2008 machine and I can send out and receive in but no one on the domain can send to eachother. I could at one time but I made changes trying to get the outbound to work. Now local is not working. What do I need to add in the exchange console to allow local emails? The error I get if I try to send an email to myself is the following:

Outlook builds a name cache list.
It's called Outlook.nk2 it's located in the:
Every internal recipient ever used, is cached in the file using their LegacyExchangeDN. When it changes then these problems occure...

Check the users all have SMTP e-mail addresses associated (check Active Directory & Exchange System Manager)

I'd delete your existing SMTP connector and re-create double checking the values so you know its 100%.

Easily manage email signatures in Office 365

Managing email signatures in Office 365 can be a challenging task if you don't have the right tool. CodeTwo Email Signatures for Office 365 will help you implement a unified email signature look, no matter what email client is used by users. Test it for free!

Did you migrate the user(s) from another Exchange server?
It looks like it tries to send the mail to a wrong LegacyExchangeDN. Make sure users are not using they're cach to send e-mail. To be sure, use OWA and select the user from the Address Book.

No I didn't migrate, the accounts are online. I was able to send successfully through owa. Hmmm... I was trying to send through outlook over http. Is there a file i need to delete out of the outlook file to clear the cache?
cnmgtAuthor Commented:
Can i simply delete it?
Yep no problem. Users may complain...
What the NK2 file does, is autocomplete names. When beginning to type in the To/CC field in Outlook, you get a list of names you ever mailed to.
When the file is deleted, the NK2 file will be rebuilded after sending the first mail.

I have another question. Since this installation of SBS 2008. When we add computers onto the domain and setup outlook on the domain. We receive a standard certificate error asking if we want to continue to the connect and then it asks for a username and passoword. It shows the certificate name at the top as however our certificate is If you click to view the certificate it is right but somewhere outlook or exchane thinks it's suppose to be remote.
cnmgtAuthor Commented:
The error says
"The name on the security certificate is invalid or does not match the name of the site.

The certificate is right. If possible how do I change the name of the site?
cnmgtAuthor Commented:
I've resolved half of the problem. During the install when you go through the final list of items to be completed, when you lick on the setting up web presence it creates a prefix "remote" to the domain name. I simply had to change that to mail. However, my computers on the domain still window to sign in when they launch outlook. If you don't input your username and password, you can still send and receive but keep getting prompted to input your domain username and pasword. Where would this authentication setting be located?

Check the internal server URLs on your CAS server.
You can check what happens if you hold CTRL -> Right click your Outlook icon besides the clock -> Test e-mail autoconfig...
User autodiscover and see which URLs are published by your CAS server.
