Ok, so that confirms that issue is within the hybrid move.

I'd be interested to see if the remote move is hiding the object from address book (very unusual). From Exch 2007/2010 powershell, run:

Get-RemoteMailbox <O365_migrated_mailbox> | select HiddenFromAddressListsEnabled

By default the output should be 'False', but if it's 'True' that explains why you're facing this issue. And if this is the case, one O365 migrated mailbox would not be able to see the second O365 migrated mailbox either.

ok.

The Powershell command don't run in my exchange 2007

When run in exchange 2013 display no hidden mailbox.

But.

I saw in one of my outlook client in my on-premise exchange 2007 when change the address book and select "All User" the mailboxes migrated to O365 display there, but not in "Global Address List".

That is good news because when migrate department my people can use "All user" to find that mailboxes migrated until the migrations complete done.
