Exchange 2007 Get-Recipient does not return all results

I just ran into a strange issue with the Get-Recipient commandlet from Exchange 2007 SP3.  I am no PowerShell guru, but it is my understanding that by just running the command, I would get a list of all recipients in the system:

     Get-Recipient (with no parameters)

I ran Get-Recipient | Sort-Object Name | Select-Object Name,RecipientType

When I look at the resulting list, I noticed some users were not on that list.

If I add some parameters to the Get-Recipient command to specifically look for that user, they show up.  For example:

     Get-Recipient "lastname*" | Sort-Object Name | Select-Object Name,RecipientType

or even

     Get-Recipient * | Sort-Object Name | Select-Object Name,RecipientType

The question I have is, why aren't the users showing up by just running Get-Recipient?

Get-Recipient -ResultSize unlimited | Sort-Object Name | Select-Object Name,RecipientType

You have to use the _resultSize to unlimited as by default its for 1000

Thanks Rancy.  That seems to have resolved my issue.

I admit though I'm still baffled by one thing.  It would appear that when MS made the Get-Recipient commandlet, they made it perform differently when using a wildcard vs. without.

For example:

Get-Recipient -ResultSize Unlimited | Select-Object -First 10
Get-Recipient * -ResultSize Unlimited | Select-Object -First 10

I get a completely different list of items with both of these queries!  Any idea why that is?  Of course that's out of scope for my original question, but just curious.
