Just run a one or two test mailboxes. That'll make it pretty clear. Regards,

The trusts have been successfully established and DNS is working properly between the two forests. I know Exmerge is still an option for this, but not for sure how well this works with this type of setup. Plus I think that the user will not get any new e-mails come through until the PST file has been imported into the new mailbox on the 2010 server. Also know about the New-MoveRequest cmdlet for EMS, but not for sure if I need to use the ADMT tool to migrate user attributes over before the mailbox is moved. I am just confused right now and looking for some pointers. If anyone has some info about this, I would appreciate it. Thanks for your feedback.
