Followed https://technet.microsoft.com/en-us/library/ee861103(v=exchg.150).aspx to move mailboxes cross-forest between 2 EX2013 servers. Pull migration.

The moves pause for several hours at 99%, and ultimately complete with CompleteWithWarning status. So far, it happens every time. Occurs even with mailboxes created and immediately moved, so it is not a problem with specific, perhaps corrupt mailboxes.

Get-MailboxStatistics -IncludeMoveReport tells me this:

Warning: Unable to update Active Directory information for the source mailbox at the end of the move. Error details: Not connected.

There's a bi-directional forest & domain trust that appears to be working, cross-forest DNS works, and it's able to "connect" to AD in the remote forest for purposes of moving the mailbox, so I'm not sure why it's finding it's "Not connected" when it cleans up at the end.

After the move request goes from 99% to 100% (after a lengthy timeout), the source mailbox still exists, and both source and destination mailboxes can be logged on to. My understanding is that the user account in the source forest should be converted to a mail-enabled user.

I'm OK with troubleshooting and solving this if it's fast. But I'm also OK with writing a PowerShell script to post-process the user account in the source forest to get over the hurdle, since this is a one-time process...the source forest will ultimately go away.

So I'm guessing the script will be as simple as--

Disable-Mailbox someuser@domain.local

Enable-MailUser someuser@domain.local

Also, I'm not clear on whether this is relevant to the MEU, but inbound SMTP will continue to go to the source mail server until migration is complete, so the source server needs to redirect mail for moved mailboxes to the destination server. Both servers have the same external domain. I'm thinking this ends up being handled by a Transport Rule I can create in the same script, so the internal, secondary SMTP address stamped on the mailbox by Email Address Policies should do the job. But if there's something I need to include in Enable-MailUser, please advise.

Hi,

Please run the following command to check the mailbox in the resource forest and target forest respectively:

Get-Mailbox User | fl

In the Active Directory Users and Computers of the domain controller, please right-click the User and check the Exchange properties in Attribute Editor tab.

Additionally, please confirm if you have deployed Microsoft Identity Lifecycle Manager (ILM) for cross-forest global address list (GAL) synchronization or created the target mail user using an Active Directory tool other than ILM/MIIS before the cross-forest migration. For more information about Prepare mailboxes for cross-forest move requests, Please refer to:

Hi Winnie, thanks for your reply.

Nothing jumps out at me when checking Exchange AD attributes, but that's at least in part because there are so many of them. Needle in a haystack. If you can tell me what I'm looking for, I will be happy to take another look.

ILM is not in use. Prepare-MoveRequest.ps1 created the new user account.

That's correct the source mailbox server should be converted to a meu as part of the mailbox move completion process. As far as routing, yes inbound mail comes to your source server still and then redirects to your mailbox enabled user in the new forest based on the source meu's external target address. During transport coexistence, you would've needed to create a new smtp domain for the new forest such as a temp one ie. @myinternaldomain.com since both forests are are using the same smtp namespace. This temp @myinterndomain.com would be binded to the new mailbox enabled users in the new forest so that the meu in the source can forward to this address.

As far as your source mailboxes not being converted and hanging at the end seems like a bug, are you on the latest cu7?
