We have a mixed installation (UM/VM) of Unity 5 integrated with Domino 7. We have a couple hundred UM users working happily, and are rolling out VM-only boxes to users at this point. This morning's roll-out included a couple of users who report that they are getting MWI notifications for e-mail return/read receipts. They are not getting notified for e-mail in general, and the TTS box is greyed out in Unity Admin.
Any suggestion for how to make these extra MWI notifications stop? Any assistance is appreciated.
