Host multiple domains

[HKNinja]

For some technical reasons, my new company is still using Exchange 5.5 and NT4.0 servers. The Exchange server is right now hosting company A's emails. Our corporate recently purchased a new company (call it company B)and this new company is using POP3. We want to host Company B's email on our Exchange server as well and get rid of the POP3. Can anyone give me some pointers as Exchange 5.5 is too old for me to handle. Thanks!

Once you have created the new mailboxes on your exchange server, you need to decide whether you want Company B's mailboxes to remain with their own domain e-mail addresses, or share Company A's.

If you want mailboxes addressable only by user@companyA.com and user@companyB.com and no mixing between the mailboxes, then simply add company B's domain to the Routing tab in the Internet Mail Service as <inbound>. To have a mailbox addressable from both domains, you'll need to add e-mail addresses for both domains to it.

If you want all mailboxes for both companies to receive e-mails at both user@companyA.com and user@companyB.com then you can add company B's domain to the Routing tab but route to company A's domain. Then you only need e-mail addresses in each mailbox for Company A, and they'll also receive any mail sent to the equivalent e-mail address for Company B.

Thanks Griffyn, that works. However, I'm having a problem with this mutliple domain email situation. Here is the story:

John Smith has emailbox jsmith@CompanyA.com and jsmith@CompanyB.com. The two companies are under the same corp but operate as seperate companies. With the relaying, John can receive the emails no problem. But when he send email out, he need to send them via the right channel. So, emails that go to CompanyA's clients should show jsmith@CompanyA.com and the same way with CompanyB clients.

Problem: there is a limitation on Outlook to connect to only one Exchange account per profile. Any good solution to this situation?

You can have multiple mailboxes associated with a user - just give those mailboxes the same permissions. Then in the Outlook setup, you have one of those mailboxes as the Primary mailbox, and you can add multiple additional mailboxes. In Outlook 2003, that would be, Tools, Email Accounts, View or Change..., click Change, click More Settings, click Advanced tab, click Add button and choose the CompanyB mailbox.

Then, to choose the CompanyB mailbox as the sender, you need to be sure you can see the From field (click View, From Field), and then type the name of the CompanyB mailbox. You may want to append (B) or something so that you can tell the difference between the two.

Thanks, Griffyn. That works beautifully. Only problem is when using the form field, recipient that uses Outlook will see "Send on behalf of" message.
