Public Folder Migration to Office 365

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

Any help or guidance is very much appreciated.
