Exchange 2003 Public Folders

[sanjivb]

Hi,

I am having an Exchange 2003 organisation running in mixed mode with 3
Exchange 2003 servers( FE-BE architecture) and one exchange 2000
server.

The problem that is being faced is users can access public folders
thorugh OWA. But they can't access them using mapi clinets.

The error that they get is "Unable to expand the folders.The set of
folders could not be opened. The attempt to logon to Microsoft computer
failed."

This was working for a month and started the problem when we
decomissioned a standy Exchange 2003 server from the organisation.

Any inputs / suggestion are highly appreciated.

Thanks,
Sanjiv Bhor
