We are having a problem intermittently with MWI. We noticed the problem yesterday.
Problem: Some users noticed that they had messages, but their light was not on. To verify, I logged into their mailbox and marked a voice message as unread and watched the Port Status Monitor for the MWI to go out... Nothing.
Supporting info: Other users in the same mailstore, same Active Directory OU, and had the same permissions were working fine. I had at least 3 users experiencing this problem.
Solution: Restarting the AVMsgStoreMonitor service ultimately fixed the problem.
Question: I am trying to understand WHY this happened, and how can I monitor for this if it happens again.
This states that this problem can occur if the mailstore that the Unity subscribers are located on is dismounted and re-mounted. Our Exchange team confirmed that they did dismount and re-mount the store last weekend which fits into the timetable for when the problem started.
FIX: Restart the AvMsgStoreMonitor service. This is first fixed in 4.3(0.25).
Any thoughts about why the AvMsgStoreMonitor service would not recover from the mailstore being remounted?
