Public Folder Migration to Office 365

Question

I am performing a Public Folder Migration to Office 365 according to the steps at http://technet.microsoft.com/en-us/library/jj983799(v=exchg.150).aspx#Scripts. I made it down to Step 5, substep 5 where we are supposed to start the migration with a
New-PublicFolderMigrationRequest. The script fails with the following error message:
Starting a command on remote server failed with the following error message : [ClientAccessServer=BN1PR07CA0067,BackEndServer=co1pr07mb395.namprd07.prod.outlook.com,RequestId

. For more information, see the about_Remote_Troubleshooting Help topic.
    + CategoryInfo          : OperationStopped: (System.Manageme...pressionSyncJob:PSInvokeExpressionSyncJob) [], PSRemotingTransportException

Any help or guidance is very much appreciated.

Answer 1

So...I double-checked the authentication setting on Outlook Anywhere...it says Basic. But, when I changed to NTLM in the command line, it seems like it is working. However, now I get the following error:
The specified mailbox "Mailbox1" doesn't exist.
    + CategoryInfo          : NotSpecified: (:) [New-PublicFolderMigrationRequest], ManagementObjectNotFoundException
    + FullyQualifiedErrorId : [Server=CO1PR07MB395,RequestId=e9e9e242-9b1c-46ad-8f0f-375eeb0d5527,TimeStamp=10/31/2014 1:47:31 PM] [FailureCategory=Cmdlet-ManagementObjectNo
   tFoundException] 933A0896,Microsoft.Exchange.Management.RecipientTasks.NewPublicFolderMigrationRequest
Any assistance would be greatly appreciated.
Thanks,
