hello, lately we upgrade our domain to 2008 R2 DC's, Exchange 2007 Sp2, & now exchange 2010. struggling with the EX2010 we have few problem that can't point my finger on: mail is working between 2010 & 2007, certificate is set, OAB all is ok. working form OWA the Free/busy is working, however Public folder can't be access "Error ! The public folder you're trying to access coulnt' be found. For mor information ,contact your helpdek." external outlook client (RPC over Http) Free busy not woring, however public folder working.. help

A - Do you have a replica of the \non_ipm_subtree public folders on Exchange 2010? B - Do your users have unobstructed MAPI access to the mailbox Servers? For most MAPI clients use the Client Access server, but for Public Folder access they contact the Mailbox Server directly. Mike Crowley Check out My Blog!

try this instead: Open Exchange Management Shell change change the path to drive:\Program Files\Microsoft\Exchange Server\V14\Scripts Type .\AddReplicaToPFRecursive.ps1 -TopPublicFolder "\NON_IPM_Subtree" -ServerToAdd "exchange2010" Mike Crowley Check out My Blog!
