MWI Status is Off

Under Subscribers>Messages, I see that Status is Off and there is a "X" . Wonder why this status is off ? refresh it does not help. Does it suppose to be "On" ? Please help. Thank you very much.<br>Duc Vu<br><br>

Re: MWI Status is Off

The X does not signify the state of the MWI. The X simply directs the system to control the MWI of the subscribers DN.

Re: MWI Status is Off

This field can be somewhat confusing, here is my best explanation of how it works:

The MWI status field represents what Unity believes the state of that subscriber's lamp to be. Thus, if the subscriber has new messages in the Inbox, and Unity has attempted to light the lamp, the status will say, "On". If the subscriber has no new messages, and Unity has tried to extinguish the lamp, it will say, "Off".

There isn't any way for Unity to actually verify the state of the lamp, but in most cases the status should match the actual physical condition of the lamp. If you press the Refresh button, it will send an off code, followed by an on code if the subscriber still has new messages.

There are a number of things that can interfere with MWI accuracy. If the lamp on/off codes Unity sends are incorrect, Unity will think the lamp is lit once the code has been sent. If Unity believes the lamp is already lit, and another new message comes in, no new MWI attempt will be sent. If there are not enough MAPI resources for Unity to monitor each subscriber mailbox, Unity may not realize a subscriber has new messages, so no codes would be sent. Mainly, that status field is used to help troubleshoot MWI issues by checking it against the actual lamp on the phone.
