Office 365 Staged Migration
Im about to do an Staged Migration from an Exchange 2007 to Office 365.
Im following this from Microsofts TechNet: http://technet.microsoft.com/en-us/library/jj874018(v=exchg.150).aspx
But in Best Practice in the bottum of page it says:
Inform users before you start the batch, because they'll stop receiving email sent to their on-premises mailboxes soon after the TargetAddress property is configured to forward mail to their Exchange Online mailbox.
Why does the On-Premises server stop receiving mail then i havent moved the MX record?
I trought I could create all the users and then sync all the email, test if it works on Office 365, move the MX and then make a final sync.

Okay, thanks! :)
Also a quick tip: don't trust the GUI. Especially for the mailbox delegation. If you select 5+ users to have Full Access it won't place all those users into the mailbox delegation settings. Powershell is your friend.

For this?
The following list shows the administrative privileges required to migrate mailboxes using a staged migration. There are three possible options.
¿ The migration administrator must be a member of the Domain Admins group in Active Directory in the on-premises organization.
Or
¿ The migration administrator must be assigned the FullAccess permission for each on-premises mailbox AND the WriteProperty permission to modify the TargetAddress property on the on-premises user account.
But the GUI have allready screwed me. It wont accept my CSV, and the log says absolute nothing, I can use. So now I will try PowerShell (Without the auto-start feature).

Right now I have made an DirSync and was about to make a staged migration, until i read that then the sync is done, the on premise would be deactivated and only Office 365 would work.
As I said in my first post, I tought I could test public folders, shared folders, mailbox etc. before i reconfigured all the clients.
