SBS 2008 - POP3 Connector breaks when changing users return address.

I'm having problems configuring the POP3 Connector in SBS 2008.

I've set up a small office with 3 users. This is a small subsiduary of a larger company.

For various reasons I wont get into and have no influence over, all emails are distributed from the parent company via pop3.

I've setup the server with a domain smallsubourcompany.com but I want all the email addresses to appear to come from ourcompany.com.

In the Windows SBS Console, I enable pop3 connector and configure pop3 access for the users and test - All works fine.

I then go into Exchange Management Console and make changes so the reply address in 'Mailbox/User/Properties/E-Mail Addresses' is name@ourcompany.com instead of smallsubourcompany.com but on testing the Pop3 Connector fails with...

(Event 203 : "An error occurred while delivering mail to 'robert@ourcompany.com' on the SMTP server 'localhost'. The error code was 0x800ccc69. Verify that the mailbox exists and that the Exchange receive connectors are configured properly.")

Anyone know what's going on and how I can get around this?

I've been through all of

and nothing makes any difference.

I've tried reselecting the 'mailbox' for each user in the POP3Connector dialogs but that doesn't work either.

If I change the return email address back to the default, the POP3 connector springs back into life.

> "Do you have the domains as ' Authorative Accepted Domain' ? (organisation>hub transport> accepted domains)."

Only companyB.local and companyB.com have been set up. Both are authoritative and companyB.local is set to default.

- Adding companyA.com to the list seems to have fixed things.

Thanks.

Gah!

Now can't send emails from CompanyB to CompanyA by adding CompanyA to "Authorative Accepted Domain" list.
