Good Afternoon,
I am looking for a bit of help as I have been tearing my hair out over this.
I am looking to move a bunch of mailboxes cross forest from a legacy Exchange 2007 forest to an Exchange 2010 forest. The accounts had already been prestaged so the prepare-moverequest script was out. I was then going by the information on http://www.experts-exchange.com/Software/Server_Software/Email_Servers/Exchange/Q_27403059.html which said that I need to create a mailbox for each of the users and set the guid and proxy addresses to be the same ont eh new environment as they were on the old. I have done that however all I ever get from the new-moverequest command is targer user already has a primary mailbox which it does but I have no idea of how to get round this and for the new-move request to merge the mail data into it or overwrite it.
Any help would be greatly appreciated.
