setting a sub-business

Last Modified: 2012-05-06
My company is setting up a subcompany. They want it to have its own domain and email address. It is going to need access to some resources on my network. I know I can set it up as a sub-node in my AD, but how does that work with exchange? Would I just create mx recods that pushed the email to my domain and then have it push from there? I am a microsoft network 2003 r2, exchange 2003. If anyone could point me to some articles that would help I would greatly appreciate it. I am currently combing my admin handbook for 2003 ad.

need to configure exchange to accept mail from each domain (exch system manager -> recipients -> recipient policies -> default policy -> email addresses (policy) tab -> add your domain). [http://techrepublic.com.com/5208-6230-0.html?forumID=101&threadID=219961&messageID=2255844]

You'll setup separate mx and a records for your new domain and point them to the common Exchange server.  On the Exchange side of things, you'll have to setup a second recipient policy per fnbqppl.  Do you need isolation between the two companies?  If so, you might be better off setting up a separate Exchange server in it's own Org for the sub-company.

The degree of separation required is based more on Accounting then law. I should be able to control it through rights across the WAN. I've done the setup I listed above, but I am struggling to setup the subdomain. We have yet to select a vendor for the website build and hosting. But when that is done I'll construct the mx records. Do I need to construct the mx records with a different weight than my main mx records? Thanks for the help.

Mailflow will be independent of the website build and hosting.  You should be able to do a full test run of your email infrastructure as soon as your RUS runs and the DNS mx records are added.

You can use the same mx weight(s) as your current mx.


I am not sure that I follow. I do not host my own dns and mx records. Would I change my current mx records in some way?  Currently my new domain is not pointing anywhere, wouldn't I need that fully hosted in order to redirect?

Does your existing company already have an internet presence and is someone hosting your DNS entries?  If so, you should be able to setup and test your Exchange service for the sub-biz by just:
1) Adding an additional SMTP to your users (via RUS)
2) Having your ISP (or whoever hosts your current domain) establish new domain records and add new MX and A records for your Exchange server

Once these two actions are done, your sub-biz users can use email using their own SMTP suffix.  The point is that you can get your email infrastructure up and running before the website build.


Thanks paired with the server config this is working great.
