The Public Folder databse is somehow corrupt/unusable. The symptoms are: 1. Cannot navigate to/acees PF on E2K07SP3 from an Outlook 2007 client. 2. When viewing PF with EMC/Toolbox/Public Folder Mgt Console, the contents of Default Public Folders and System Public folders is not displayed 3. If try to add a folder in PFMC, get an error: The operation cannot be executed because there is no available public folder database on the server 'EX2008'. 4. get-publicfolderstatistics returns the following: Name ItemCount LastAccessTime ---- --------- -------------- EX:/o=First Organization/ou=Exchange Adm 15 2/19/2011 12:26:54 PM inistrative Group (FYDIBOHF23SPDLT) EX:/o=First Organization/ou=Exchange Adm 0 2/19/2011 12:26:52 PM inistrative Group (FYDIBOHF23SPDLT) globalevents 0 2/20/2011 11:27:29 AM internal 0 2/20/2011 11:27:29 AM OWAScratchPad{807A6098-6839-4C6F-BA33-D2 0 2/20/2011 11:27:29 AM E1A67E1AEB} StoreEvents{807A6098-6839-4C6F-BA33-D2E1 0 2/20/2011 11:27:29 AM A67E1AEB} /o=First Organization/cn=addrlists/cn=oa 0 2/19/2011 12:26:54 PM bs/cn=Default Offline Address Book 4.

Hi BSUNIC, Could you please describle more detailed information about your scenario Could you please confirm the public folder database is mounted well? How about run EXBPA to confirm more informaton? Some suggestion for you: 1. I would create a new publicfoler database to make a test. 2. If there are publicfolder already creted, and work well before, we could use isinteg to fix the database, and then mount it. Regards!
