Using Exchange 2010 mailboxes on 2 Trusted Forest

My organisation has 2 separate Active Directory Forest in 2 different geographical sites, ABC.com and DEF.com. Both have 2 way trust established.
An user A is currently in ABC.com but will be relocating to DEF.com. He will be spending 50% of his time at both sites. However, he wants to maintain his email account in ABC.com such that he can send and receive on DEF.com.

My plan is to create Forwarding on Exchange Server on userA@ABC.com to userA@DEF.com.
Thus all his incoming emails will be forwarded out to userA@DEF.com.
When he is in DEF.com site, he will connect to userA@DEF.com and SendAs userA@ABC.com.

Just 2 issues I have problem with-

1. Can I setup Outlook 2010 on DEF.com to SendAs default userA@ABC.com when he is in DEF.com domain? I want him to be able to send using userA@ABC.com without having to switch the From: every time he sends email.

2. How do I route his sent items such that he when he sends out from DEF.com as userA.ABC.com --> A copy is kept on userA@ABC.com in his Sent Items?

Hi Frukeus,

I think it is not possible the way you want it. You can configure transport rules etc, but it takes a lot of configuring to do without all the functionalities.
What you can try is using Outlook 2010. Now you can use multiple Exchange accounts with 1 Outlook profile. You still have to choose from which account to mail from, but he has all his information without to much trouble...
Hope this will be sufficient for you.

Regards,
BB

Sorry, I need to clarify. He does not require to use the same Outlook program at both sites.

In ABC.com, he will use a PC that has Outlook 2010 configured for ABC.com.
Similarly, in DEF.com, he will use another PC with an Outlook 2010 that is connected to DEF.com's Exchange.

I only need to have all his emails (incoming and outgoing) available on both mailboxes in the 2 different Exchange Servers and able to send as UserA@ABC.com on both sites as a default.
Default sending from is (by my knowledge) not possible to change to something else as the account you're connected to.
You could create Transport roles to send copies of every mail from and to him. But those e-mails will all be delivered as normal e-mail in the inbox.
So I think it is not possible, if you however find a solution to do so, please let me know.

Good luck!

I've managed to configure exchange account from forest DEF.com to send as userA@ABC.com and route the mails from ABC.com to forward to userA@DEF.com.

Thus emails sent to userA@ABC.com will be forwarded over and when he replies from userA@DEF.com, it also reflects as userA@ABC.com.
