Exchange is on win server 2008
I put migration tools on exchange server.
But on the second step ‘SOURCE’ ,to login exchange cannot pass.
I entery the exchange server IP but whatever I used domain user 'Administrator@****.com' OR local user 'Administrator' ,it's always 'Directory Object cannot be opened ,please verify the used admin cerdentials'
And I try to user the AD server IP ,when i used user 'Administrator@****.com' it's said 'please check the admin cerdentials for permissions/right to query the directory' , when i change teh local user 'Administrator' it's said 'Exchange mailbox profile creation error'

How can i solved it?

migration tool version is ZimbraMigration_8.0.5.993_x86.
