Exchange 2010 public folder default quotas

I have been looking high and low for this information and can't locate it anywhere.   Does anyone know what the DEFAULT quota settings are for the public folders in Exchange 2010?  I know they started setting defaults in 2007, but I can't find what they are in 2010.  You would think this information would be fairly easy to find, but no.  Thanks.

Yes, I know this is an old post, I’m trying to clean up older posts that are unanswered.
Did you ever figure this out?

no, i never did find an answer.

I'm not an exchange guy but seen item 8, don't know if it helps.

This still doesn't actually give a number.  I remember I was able to finally ballpark a number enough to move on with what i needed to do, but I still have not found any iron clad number, but thanks anyway.  I appreciate your help.  : )
