I have On-Premise Exchange 2007 with Exchange 2013 in Full Hybrid O365.

All users mailboxes reside in E2007, I migrate two mailbox to O365, when complete the migration if one user in the On-Premise E2007 try to find that migrated mailbox the user not display in the Address Book, but the two mailbox migrated saw mailbox in E2007 and O365.

 

What need to do to my E2007 users look O365 user mailbox in O365? (using E2013)

 

Thanks!

@Edwin Cruz: Try moving a mailbox from Ex2007 to Ex2013, and check if you're able to see that migrated user from an Ex2007 user's Address Book. This will help determine where to focus the troubleshooting.

If that works, now migrate that same mailbox from Ex2013 to O365 and verify Address Book lookup again.

ok.

 

I created a exchange 2007 mailbox, then migrate to exchange 2013 and work fine, people in 2007 saw that mailbox in 2013 and that mailbox saw exchage 2007 mailbox.

 

but!, that mailbox in 2013 don't see a mailbox in O365, and that O365 mailbox user see that mailbox in exchange 2013 and 2007

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.
