I have RPC-http for Exchange. It has been working fine for months. Today, I am no longer able to use RPC for Outlook. OWA works, windows mobile connects, and over the network are all working. I have not made any changes to Exchange.
the only change thar I can think of is that I just set the domain to use NTLMv2 and to disregard other methods of hashing. Could this cause this issue?
