I am working on Exhange 2007/2007 migration.

Replicas of the public folders were created on the new mailbox server.

Config is clustered mailbox server and cas/hub transport using
ISA2006 to publish.

The problem is my users on the 2007 server cannot see Public Folders
using Outlook anywhere. They can see them from OWA and from internal
network but not from Outlook Anywhere.

A dialog pops up with: The set of folders cannot be opened. Microsoft
Exchange is not available. ...... (o=XXX, First Administrative Group
/cn-............. /cn=<2003 server)

It seems that AD is still pointing to the public folder store on the
2003 Exchange server.

Everything else is working ok

Any ideas?

Thanks,
Mark
