I have configured an Exchange 2007 based system with Unity Connection (7.1.3), though some basic integration features are working, I am having problems with the below
1) From PCA I am unable to syncronize the contacts. the error i get is "Import Contacts from Exchange Server Failed"
2) I can access the mails in the exchange message store, but the functionality is limited for example from a list of saved messages, unity conn. will read only the last saved message and then it does not prompt or move to the next message.
Note that when testing the user settings for external services I get a specific error, The system failed to perform a typical calendaring operation" in error details i see "The system failed while trying to make an API call".
