I am faced with an issue when adding a subscriber from notes 6 to Unity 4.0(4) running DUCS 1.2 the process fails giving " unrecongnised error 0x80044605 has occurred. The new subscriber was not successfully added"
I looked at the event viewer and see the error message "This subscriber's mail server "%2" is not a member of the "%3" Notes Domain"
It also seems that the Domino server is version 5, but the Notes client is version 6.
Any ideas where I should start troubleshooting this. I am yet to determine if any software changes have been made lately.
