Exchange 2003 to Exchange 2010 Co-Existence Questions
Hello Experts,
I just installed 2 new Exchange 2010 SP2 RU8 servers in Co-Existence with my existing Exchange 2003 environment. Following a great guide So far so good. I just ran into a small (I hope) hiccup and have a few questions:
Hiccup/Question
In testing the creation of a new mailbox on EX2010 i am only presented with my internal AD name for the @ part i.e. my only option is @rds.contoso.com (AD ROOT) but we use @contoso.com. In EX2003 we have all domain variations listed and created for each user listed and default it to @contoso.com for new users. Is there a configuration i have to perform to get those to come over to EX2010?
****Also the other domain variations are listed under Accepted Domains****
Other Questions:
1. I am using a new public name for access for example we currently use webmail.contoso.com to access OWA/ActiveSync/RPC but i have all the CAS services publicly pointing to mail.contoso.com Since we are a fairly small business (75 users) i can easily direct folks to the new mail.contoso.com once i move this mailbox to the new exchange server. Is there any need to setup Legacy redirect then?
2. If i only have 1 CAS 1 HUB and 1 MB do i still need to setup CAS array in active directory or can i wait until i deploy to our Branch Office?
3. If i do have to perform the CAS array setup now will that impact existing RPC client connecting to the EX2003 frontend server?
Thank you!

Input:
Configure the Exchange 2003 URL property on the /owa virtual directory. This is necessary for Exchange 2003 and Exchange 2010 to coexist. To configure this property, use the below command.
Set-OWAVirtualDirectory <CAS2010>\OWA* -Exchange2003URL https://legacy.domain.com/exchange
2. If i only have 1 CAS 1 HUB and 1 MB do i still need to setup CAS array in active directory or can i wait until i deploy to our Branch Office?
Input:
If your planning is to use single Client access server even in future then you don't need to configure CAS Array.
3. If i do have to perform the CAS array setup now will that impact existing RPC client connecting to the EX2003 frontend server?
Input:
No it will not.

I created it with the rds.contoso.com for the email and when i checked it auto listed the accepted domains and listed the @contoso.com as the default email address so seems to be working as expected.
