Unable to access Public Folder in Exchange Server 2010 SP2 with Outlook 2010 ?

Hi people,

All in a sudden everyone on the domain cannot open the public folder with the following error message:

Pop Up:
Cannot expand the folder. 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

Outlook client background:
Cannot display the folder. Microsoft Outlook cannot access the specified folder location.

There were no maintenance or update being applied in the past months on the following Exchange Servers:

PRODHT-CAS01 (HT-CAS Server NLB node 1)
PRODHT-CAS02 (HT-CAS Server NLB node 2)

PRODMBX01 (Stand alone Mailbox Server 1) no DAG
PRODMBX02 (Stand alone Mailbox Server 2) no DAG

the work around was to restart the Microsoft Exchange RPC Client Access service on PRODMBX01 mailbox Server that I took to resume access to the Public Folder.

the question is why do I have to do this all in a sudden ? what may have caused it ?

Are you running Windows 2008 R2 Domain Controllers by any chance? They tend to go flat with CPUs causing all sorts of email issues sometime. If this is the case you didn't have reset the RPC client access service on the CAS boxes, rather a RC reset was required to resolve this issue.

ok, the solution was to reset the MS Exchange RPC client Access Service.

After that everything works normally as it should.
