upgraded Unity to 7.0 was unified and still unified. Since then mwi does not work properly goes on for some not others goes off for some and not others. No rhyme or reason. If you look at the subscriber and messages mwi is pending. You can refresh until the cows come home. And then the next day clears. Added 5 ports for mwi so I know it is not a matter of not enough ports because once the problem occurs on a subscriber I can run port status and hit refresh and nothing. Is it possible to have some kind of AD policy that could cause this. thx again. P.S. CSS and partitions are absolutely correct. I got so fed up I said dial anything you want.
