How do public folders work in Exchange 2013?

Solution 1:

Massimo,

I had actually wondered the same thing while attending an online "lunch and learn" a while back and was pointed here: http://blogs.technet.com/b/exchange/archive/2012/11/08/public-folders-in-the-new-office.aspx

The basic premise from what the guy told me (and the article confirmed) is:

1. Each public folder mailbox created contains info on the full hierarchy of the PF structure (folders, subfolders, etc.)
2. A public folder mailbox contains one or more public folder's content.
3. If the content, let's say "QUOTES" gets too large for the mailbox it is spawned off into a new PF mailbox where it now holds the content and a copy of the hierarchy. The client won't know and doesn't care.

So to answer a few of your questions:

Where is the PF content stored? In one or more PF mailboxes

Can I place different PFs in different mailboxes? Yes
