create "public Folder(Contact)" by using webDAV - Microsoft Exchange

One of your property names is wrong should be outlookfolderclass not
outlookfoldersclass eg something like

<aropertyupdate xmlns:a="DAV:"
xmlns:ex='http://schemas.microsoft.com/exchange/'>
<a:set><arop><exutlookfolderclass>IPF.Contact</exutlookfolderclass></arop></a:set>
</aropertyupdate>

I wouldn't worry about setting the displayname its will use the name from
the URL.

Cheers
Glen
