I recently upgraded our Exchange 2010 from rollup 4 to Service Pack 1, rollup 1.
After the upgrade users can no longer open public folders using Outlook. Instead, they see this error:
The set of folders cannot be opened. Microsoft Exchange is not available . Either there are network problems or the Exchange server is down for maintenance. (/o=DOMAIN/ou=Exchange Administrative Group (....)/cn=Configuration/cn=Servers/cn=MAILSERVER1)
Public folders can still be opened using OWA. We are using Outlook 2010 on the desktop. Any suggestions?
I tried using the new Public Folders Management tool in Exchange Management Console. When I click on a public folder and try to change the settings on it, I get this error:
Microsoft Exchange Error
Action 'Update Content' could not be performed on object '_Blah:SampleFolder'.
_Blah:SampleFolder Failed Error: Cannot start content replication against public folder '_Blah:SampleFolder' on public folder database 'Public Folder Database'.
MapiExceptionNoReplicaAvailable: StartContentReplication failed. (hr=0x80004005, ec=1129)

OK
We've also (unrelated?) had two blue screens on the Hyper-V server hosting our Exchange VMs. Something I haven't seen in quite a long time.
Here is our architecture:
CAS server (hosts OWA also)
MailServer1: DB1, DB2, Public Folders
MailServer2 DB3 (also has CAS server role)
I saw this recent question: Can't access public folders after upgrade to Exchange 2010
I also have a Dell server! However, following these instructions didn't resolve the issue on my machine, and I was going from Exchange 2010 RTM to SP1.
