Get-OutlookAnywhere takes time to show comand output

I was trying the below command, to see the OutlookAnywhere information for all exchange servers, but it was taking really long time to load the information.

Get-OutlookAnywhere | ft ServerName, *auth*

Then I used the command with -AdPropertiesOnly to fetch the info quickly. This will show the information, really quick.
 
Get-OutlookAnywhere -AdPropertiesOnly | ft ServerName, *auth*
