I have next issue: i have edb file(Exchange Server 2013), and i can get mailbox guids from it. One of mailbox is PublicFolder mailbox. It's impossible to find out if mailbox is PF, or just simple user's mailbox. I already have functionality to get all information of mailbox by it's guid from AD.

string filter = @"(&(objectClass=user)(msExchMailboxGuid=" + ESWUtils.GetADGuidString(guid) + "))";
search.Filter = filter;

search.SearchScope = SearchScope.Subtree;
search.PropertiesToLoad.Add("mail");
search.PropertiesToLoad.Add("displayname");
search.PropertiesToLoad.Add("samaccountname");
...

Is it possible to find out, that guid belongs to PF mailbox, from AD?

In Exchange 2013, Public Folders are moved into mailboxes and out of their own database. Looks like the easiest way is to look at the msExchRecipientTypeDetails attribute.

search.Filter = "(msExchRecipientTypeDetails=68719476736)"

Combine that with your other search criteria.

Running a Get-Mailbox -PublicFolder on the mailbox will show the RecipientTypeDetails listed as PublicFolderMailbox. 68719476736 is the bitwise identifier that matches on the user attributes.
