Hi

We have a single domain / forest, DC's are 2008 R2 but DFL / FFL are still Windows 2003 Server, We have an Exchange 2010 org.

We have been told we need to separate out a subsection of our business into a completely separate forest / domain for auditing purposes, however we can create a 2 way trust and allow the users to continue to use our exchange servers.

My question is if i migrate the users to the new domain can i re connect them with the mailbox they originally had that is linked to their account in our current domain, if so how would i go about doing that.

Many Thanks

Yes, you can. You can leave the mailboxes in the old forest and re-home them so they point to the new user account in the new forest. You do this with the set-mailbox cmdlet against the mailbox in the old forest and add a switch to point it to the new user account in the new forest. http://mostlyexchange.blogspot.com/2013/12/convert-user-mailbox-to-linked-mailbox.html has more details.

If i migrate the accounts and SID history is enabled im thinikng the mailboxes will continue to work anyways, is that correct?

Also the accounts are members of a Universal Dist group in our current domain, once i have migrated them do i just leave the disabled objects in there or do they need to be replaced with the AD account from the new domain?

Thanks
