Exchange 2013 New-MailboxImportRequest Stuck at "StalledDuetoHA"

We've just set up a new Exchange Multi-Tenant environment on our network.  We have two servers EX01, and EX02 that are both running full installations of Exchange 2013(CAS and MB).  

I have a DAG setup between the two servers with the Active copy of the databases being on EX02.  I am attempting to begin importing PST files for a potential tenant using PowerShell.

I have created a network share on the E: drive of EX02 named "PSTs" and changed the share permissions on the folder to allow the Everyone group Full Control.  The NTFS permissions on on the share allow Administrators to have full access and the Exchange Trusted Subsystem to have read/write permissions (read this was necessary in a TechNet article).

I gave my admin account the necessary Role Assignment of Mailbox Import Export and then ran the following command in the Exchange Management Shell.

New-MailboxImportRequest -Mailbox John.Doe -Filepath \\EX02\PSTs\PSTtoImport.pst

Select allOpen in new window

The process appears to start without issue but after an hour or so appears to get stuck.  I run the following command to check the status of the import

Get-MailboxImportRequest | Get-Mailbox Import Request Statistics

Select allOpen in new window

It tells me the move is 64% complete but under status says "StalledDuetoHA".  I have waited and let the import continue but it has been 8 hours and it is still stuck on the the status of "StalledDuetoHA".  I have tried removing the request and redoing it but it gets stuck again with the same status.  I have tried removing the request, and deleting the mailbox, recreating the mailbox and trying the import request again and the same issue.

Any ideas why this might be happening?
