Help With Migration From Exchange 2007 To Exchange 2013

We have an Exchange 2007 Server with Service Pack 3 and Rollup 12 applied. I installed a new Exchange 2013 Server and then immediately applied CU3.

I am following this Technet article:

http://blogs.technet.com/b/meamcs/archive/2013/07/25/part-1-step-by-step-exchange-2007-to-2013-migration.aspx

The only deviation from the instruction I have had to do is in Part 2, section 4 “Configure offline address book (OAB)”. Instead of entering:

Get-MailboxDatabase | Set-MailboxDatabase -OfflineAddressBook "\Default Offline Address Book (Ex2013)"

I had to enter:

Get-MailboxDatabase | Set-MailboxDatabase -OfflineAddressBook "\Default Offline Address Book (Ex2012)"

I believe this is due to the fact that the writer installed from an Exchange 2013 CU1 disk and I only had Exchange 2013.

Also when I tried to run:

Move-OfflineAddressBook -Identity "Default Offline Address Book" -Server SRV-EX2013

I get the following error:

Move-OfflineAddressBook : Failed to create the 'ExchangeOAB' folder on the target server 'SRV-EX2013'. Two possible reasons for the failure are that the System Attendant Service is not running or you do not have permission to perform this operation. Error message : 'Catastrophic failure (Exception from RESULT: 0x8000FFFF (E_UNEXPECTED))'.At line:1 char:24+ Move-OfflineAddressBook <<<< -Identity "Default Offline Address Book" -Server SRV-ex2013+ CategoryInfo         : InvalidResult: (Default Offline Address Book:OfflineAddressBookIdParameter) [Move-OfflineAddressBook], LocalizedException  + FullyQualifiedErrorId : 9250969C,Microsoft.Exchange.Management.SystemConfigurationTasks.MoveOfflineAddressBook

However when I looked at the address books in EAC I could see that “Default Offline Address Book (Ex2012)” was the default and that it contained a copy of the Global Address List. So I did nothing else about it.

I am now at Part 3, section 7 “Move Mailboxes” and it keeps failing. I am using the EAC so that I at least see the error as using the powershell brings back no results. Anyway it Syncs the 18 items in the mailbox then fails with:

Data migrated: 936.7 KB ‎(959,145 bytes)‎
Migration rate: 0 B ‎(0 bytes)‎
Error: MigrationPermanentException: Error: An error occurred while updating a user object after the move operation. --> Unable to generate the e-mail address. Unable to load address module ‎'C:\Program Files\Microsoft\Exchange Server\V15\Mailbox\address\SMTP\AMD64\inproxy.dll‎' for address type ‎'SMTP‎'. Additional message: ‎'Access is denied‎'.

Help??
