I'm not really an exchange admin, and I've tried using the

```
Get-Mailbox -ResultSize Unlimited | Export-Mailbox -PstFolderPath c:\pstexport

```

commnand. Which errors out. It screams by and hits each mailbox and fails with the following.

```
Error was found for (the user mailbox) because: Error occured in a step: Approving object
An unknown error has occurred, error code -2147221219"

```

I added the user (administrator) to the

```
New-ManagementRoleAssignment -Role "Mailbox Import Export" -User administrator

```

If I do it wrong let me know. I've just been following guides like from [this site here](http://www.exchangemaster.net/index.php?option=com_content&task=view&id=151&Itemid=1&lang=en)

I really need to get this started tonight so it can be done sometime tomorrow. Until then I'm going to be exporting one at a time through the GUI into outlook then exporting to pst (which is slow and horrible doing it manual)
