1 Exchange Box, 2 Domains - One User Account

[loki]

Hey,

Are you sure the domain has been prepared? Forest Prep on the Schema master wont prepare the domains as well to the best of my knowledge. If in doubt run /preparead on the schema master in the 2nd domain (the one the exchange server isn't in). Even if it's been done you wont break anything doing it again.

I think you'll then need to add the exchange server to the Exchange specific groups that are created manually but it could be automatic. I've not had to be as complex with an exchange 2007 installation yet.

Cheers

Also, Are you running this between two forests? or 2 domains?

[Vini]

2 separate forests, each with their own domain.

F1D1 hosts Exchange. I'm wanting to create mailboxes against users in F2D2 though.

Are you using root forest trusts? Also what domain functional level are both forests running.

If you're running a forest root trust then your on 2003 native on both which is fine. If you're doing domain trusts then you might need to check your on 2000 native on both domains, again I can't remember off of the top of my head if you need to be 2000 native to do domain trusts or if you can do it from 2000 mixed.

These all pertain to exchange funtionality btw. Exchange 2007 needs at least 2000 native on both forests.

Have a read through this link btw. It's for deploying exchange 2007 in it's own forest which Microsoft definitely support and is pretty similar to what you're doing now, so what your looking to do will definitely work. It's just one of the more complax exchange 2007 deployments.

No link, but I think I've read it. Is it resource forest topology?

Both are forests are currently 2003 function.
