Change of domain name

We currently operate under the domain mycompany.co.uk, our website is
www.mycompany.co.uk, all mail is sent to firstname.lastn***@mycompany.co.uk,
however we now want to change our comapny name to mynewcompany.co.uk.  We
have purchased the domain name and I would like some guidenance on how to
reconfigure our Exchange 2003 Server to ensure we receive mail for the new
domain, and also so how to ensure we continue to recieve mail for the old
domain until we are satified we have instrcuted all our customers of the
change.

I know that I must ask our isp to create an mx record to point to our
Firewall, which has NAT'ed rules on TCP 25 to forward mail to our mail
gateway server.

I think I need to use receipient polices in Exchange server to allow me to
recive mail, however I am unsure if I create a new policy or edit the exiting
one that is already in place. 

I am also unsure how I will be able to make the switch over to ensure all
mail going from the company has the new domain name @mynewcompany.co.uk,
whilst still recieving mail as mycompany.co.uk and mynewcompany.co.uk.

Please could someone provide me with some guidance in this matter.

Thanks in advance

(if they host your DNS, which isn't necessarily the case)

Actually, you'll first have them create an A record such as
mail.mynewcompany.co.uk - then set that as the primary or sole MX record for
mynewcompany.co.uk.

You can edit the existing one to add this; I presume you want it to apply to
all recipients in the domain.

When you add the new domain to your recipient policy
(%g***@mynewcompany.co.uk) you can select it as the default. Then all new
mail going out will be from the new addresses. However, I'd do this in two
steps - first add the new domain to the recipient policy & make sure
everyone gets the correct new address. Send a test message to make sure
inbound mail works. Then after that, make the change.

Thats excellent.  Many Thanks.

My only query regarding this is as follows:

The documentation says to amend the default recipient policy, however in my
Exchange Organisation (which was upgraded from a 5.5 Organisation) The
Default policy is set with the lowest priority. We have one other policy (set
as the highest priority) so should I amend that policy instead.

The highest Policy has the following settings:

Name= Exchange Org Name
Filter Rules =
(&(mailNickname=*)(legacyExchangeDN=/O=ExchSiteName/OU=ExchangeOrgName/*))

SMTP = mycompany.co.uk

The default Policy (Lowest Priority)  has the following settings:

Name = Default Policy
Filter Rules = (mailnickname=*)
SMTP = mycompany.co.uk

So which one do I amend to make sure it affects all my users.

Also once this has updated would I then set the primary as mynewcomany.co.uk
for all may to be sent as @mynewcompany.co.uk.

Finally when I have finally contacted all our customers to inform them of
the new company name, do I remove the mycompany.co.uk and force the recipient
service to updates all users details.

Many thanks again for your time and advice.

Use whichever one you're actually using.

Yes, but I'd wait til you knew it worked to *receive* first before making
the switch.

No, I wouldn't. I'd accept mail for both domains, at least for a while.
What's the harm?

Apologies for the delayed response I was called to an urgent project and have
only just returned.

Many thanks for you help and guidance on this issue.

This Exchange discussion forum really is invaluable.

Thanks again.

You're most welcome - I'm glad everything is resolved. It was nice of you to
post back.

Note that this isn't
actually a forum - it's a newsgroup. Try using a news client, such as Forte
Agent, Thunderbird, or even Outlook Express, rather than the pretty clunky
web interface. It's a lot easier to do nearly everything that way. You can
mark messages to be watched, filter the views so you can see replies to your
posts easily, and search.

The Microsoft public news server is msnews.microsoft.com and you can
subscribe to as many groups as you like; no authentication is required.
