I have a Unity Express 7.0.2 with ES41 special patch that migrated from exchange 2007 to 2010. Apparently there are now several exchange servers. The client needed to add a new language so I had to install almost everything again (the unity and re-install the patch). Right now when I click on the messages key on the phone (CUCM phone) have a message that says "The mail server is unavailable". Also I can put messages in VM but they the message led not always work. In some cases I can hear the messages on the phones but can not erase them. Everything indicates that it is permissions problem but i do not know where to start troubleshooting.
At this stage i run the MSCW but not finish the setup because it need to run some scripts in exhange servers. I also can not run the permission wizzard with the accounts of the unity (Unityadmin, unityinstall, unitymsgstoresvc or unitydirsvc, only through an administrator account that customer have.
Can anyone help me on this?
