Hi,
When migrating to Office 365, Exchange 2010 and 2013 do not support a staged migration because:
" In Exchange 2010 and Exchange 2013, the TargetAddress property can't be modified. This is the reason that staged Exchange migration doesn't support migrating Exchange 2010 and Exchange 2013 mailboxes to Exchange Online. "

And a response on expertsexchange (http://www.experts-exchange.com/Software/Office_Productivity/Office_Suites/MS_Office/Microsoft_Office_365/Q_28275069.html) says:
"
Because as part of the migration process, the staged migration wizard will populate the targetaddress attribute with the @domain.mail.microsoftonliMy mailbox is hosted on an Exchange 2013 server and I can successfully set the attribute with adsiedit and forward mails elsewhere.
Can someone tell me:
1. What is meant by "the targetAddress property cannot be modified." - If we're talking about the AD attribute then it definitely can.
2. Is it correct that it's not supported to change this attribute? If so can someone provide me with a link to an MS article stating this as I've not been able to find one and also an explanation why.
3. May already be addressed by the answers to above but if not: Is there any harm in modifying this attribute?
Many thanks
Steve
