I have a customer that outsources their Exchange environment. They want to use the CUPS calendar integration with their provider. I actually got the certificate issues resolved with Entrust, and I can see appointments in the IPPM. However, The CUPC does not dynamically update the meeting status as I have seen with other installs. The only way to get it to show the correct status is to disable the setting in the status menu under preferences in CUPC then re-enable it. I have a feeling that my issue stems from being behind a firewall/NAT but have not had the opportunity to investigate the firewall for any such activity.
Anybody have any ideas/suggestions on how to proceed? TAC hasn't had a whole lot to offer up to this point.
Thanks for any input!
