HI All Experts:

We have two forests:

Forest A: Exchange 2003, Domain: abc.com.au, Email Naming: @abc.com.au
Forest B: Exchange 2007, Domain: abc.com, Email Nameing: @abc.com

Because the Email naming is different between these two forests. Could you tell me Can I move email from @abc.com.au to @abc.com? and how to do this?

Thanks

Sorry I forgot to add this:

** all users still stay in the Domain: abc.com.au, they still need to login domain abc.com.au
**only mailbox & public folder need to move from @abc.com.au to @abc.com
** exchange 2007 dont have user's mailbox, this is a new Exchange 2007 server.
** do I need to move all groups in AD to new exchange server? for my understand, I dont need to do ths unless we need to move all users'account to the Domain: abc.com.au


Thanks

hold on .

if your exchange 2007 has no user mailbox and it is new, why you want to create forest B?

my strategy on this is

you keep forest A as exchange 2003, domain: abc.com.au, email naming: @abc.com.au
you install exchange 2007 in forest A
you add a new email naming @abc.com in forest A and change the default to @abc.com

using this method, forest B is not a necassery and you still able to do what you want. your AD is intact, just changing your email address.

Hi Limijanan

Sorry for this. Our Sydney Branch is using Domain abc.com.au and abc.com. The abc.com is global domain for all other branch offices including our HQ.

current, our User account & exchange 2003 is in the domain abc.com.au. The HQ is asking to migrate everything from domain abc.com.au to abc.com. But for many reasons, we cannot migrate the domain in this stage, so we are going to migrate exchange 2003 to exchagne 2007 first. And the ex2007 has been installed into abc.com, and it's ready for moving mailboxes and public folders. But we still leave user's account in the abc.com.au

Can you give any information to me how to do this?

I have already read these articles.

What I have done on Testing:
I created a Testing account named Ex2003 Test (etest@abc.com.au) in the domain abc.com.au
I create a user account naed Ex2003 Test (no email enabled) in the Domain abc.com, OU: TEST

I have moved a testing mailbox from ex2003 to ex2007 by using the following command:

move-mailbox -TargetDatabase 'exchange2007\Mailbox Database' -Identify abc.com\etest -SourceForestGlobalCatalog 'abc.com.au' -GlobalCatalog abc.com' --NTAccountOU 'OU=Test, DC=abc, DC=com' -SourceMailboxCleanupOptions DeleteSourceMailbox -SourceForestCredential $SourceCredential -TargetForestCredential $TargetCredential

I got the message said: mailbox has been moved to exchange2007 successfully.

However, When I login to the ex2007.test@abc.com, I can not see the mail. It should have at least 10 mails.

The old emial address plicy is EX2003 Test (etest@abc.com.au)
The new email address policy is Ex2003 Test (ex2003.test@abc.com)

After run the command the email address automatically convert into new email address policy. I dont know whether this is a reason.

Can you help me, please?

Thanks

u need to move the account as the SSID is different

Move the user account to the target forest by using ADMT v3. For more information about the ADMT v3, see Active Directory Migration Tool v3.0.

please carefully reread this document step by step

Hi Limjianan

just as I said, we are not going to move users' account from abc.com to abc.com.au

only mailboxes & public folders need to be migration.

i think ADMT can copy the user profile to target without deleting your source user ...
just like moving mailbox across the forest, source mailbox will not be deleted.

Hi Limjianan

Thanks for your reply : )

What I have done so far:

Create a teting account in exchange 2003: abc test (atest@abc.com.au)
create a new mail user account  in exchange 2007: abc Test (add smtp: atest@abc.com.au)

move atest@abc.com.au mailbox from exchange 2003 to exchange 2007 by using following command:

move-mailbox -TargetDatabase 'exchange2007\Mailbox Database' -Identify abc.com\atest -SourceForestGlobalCatalog 'abc.com.au' -GlobalCatalog abc.com' --NTAccountOU 'OU=Test, DC=abc, DC=com' -SourceMailboxCleanupOptions DeleteSourceMailbox -SourceForestCredential $SourceCredential -TargetForestCredential $TargetCredential

after that, I checked exchange 2007, I found the mail user: abc test has been convert to a user mailbox type and abc.test@clear2pay.com also has been enabled as primary SMTP address. Exciting......:  )

However,

** I can not see the account (abc.test)  in the DC: dc.abc.com -->OU/Users. But If i do "find" I can see it in the AD, strange !!!
** password keeps same when I log into domain abc.com. However when I tried to do the email testing for this account, I found the following problem:

** I use mxgong@abc.com.au send email to atest@abc.com.au  --> no problem
** i use abc.test@abc.com send email to mxgong@abc.com.au --> no problem.
** I use abc.test@abc.com send to itself (abc.test@abc.com) --> no problem
** I use mxgong@abc.com.au send email to abc.test@abc.com --> message said: this address not existed in the server...

I dont understand why it said this address is not existing in the server, do I need to change primary SMTP to atest@abc.com.au?

Although this is not best answer, Limijanan spent lots of time for help. And I have already completely migrated mailbox to exchange 2007.
