incoming mail with communication between exchange 2003 and 2010
Posted on 2012-12-26
Since 2005, my company have one exchange 2003 on Windows 2003 Server. We use asso.local as domain. The format of the company is firstname.lastname@example.org.
Recently, I decided to create a new forest/domain newasso. Local on Windows 2008 and Exchange 2010 environnement. IT is installed on recent and efficient hardware.
Now, I have one organization :
- User uses mail with format as email@example.com
- One forest on Windows 2003 and Exchange 2003
- One other forest on Windows 2008 and Exchange 2010
- Incoming mails arrived on exchange2003
If I have well understood, Exchange 2010 uses cas for incoming mail and not smtp.
I need to have the both server as the same time for 2 months.
If one mail is not for one user that is not on exchange 2003, I would like that mail is follow and manage by Exchange 2010. Please help me
Sorry for my english !
