We are currently running a exchange 2003/2010 mixed environment. A small portion of our population has been migrated to exchange 2010 and are thoroughly testing my deployment. Due to a future groupwise connector we will not be removing out 2003 exchange server for quite some time. Replication is working well and all 2010 exchange users can access their public folder via the Outlook Web Application.
The Issue - Users cannot access public folders via Outlook 2003 or 2007 but can via Outlook 2010.
We are on SP1 with RollUp 3-v3
