We have Exchange 2007SP1 on Server 2003 with mailbox role and public folder database (Exch1), and same configure with Hub and CAS roles (Exch2).
I installed a new Exchange 2007 SP3 on 2008 R2 SP1 with mail box role (Exch3). Everything works fine, expect users at new exchange (Exch3) can not open public folder. On the new exchange, I do not have public folder database, should I create the public folder database? Do I need to add new exchange server (Exch3) on the replication from public folder management console? Is there step by step instruction to show me how to do this? Or, can I redirect new exchange (Exch3) to use current public folder database on (Exch1). Thanks in advance.
Error from user’s outlook:
Unable to display the folder. Microsoft Office Outlook could not access the specified folder location. Could not open the item. Try again.
