Unity MWI not working for some users

jsailers

Unity 4.0(5), CCM 4.1(3), Exchange Integration, Unified Messaging.

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.

Posting some Eventviewer Errors would be helpful.

There are not event logs directly related to this problem. However there are a few errors and warnings over the last few days that could be indirectly related:

Although not related to MWI, I recently seen the same error message (event ID 21000) on our primary Unity server. Consequently our Unity failed over to the secondary Unity server.

We opened up a TAC Case and they recommended we install the latest Win 2k SP4 patches and SQL Service pack. Since we installed these patches we have not had any issues.

Here is a thread of a previous conversation on the same error message:

Good luck.

was there a lan outage recently ?

Do have a failover unity configuration ?(if yes you might want to look at following bug )

http://www.cisco.com/cgi-bin/Support/Bugtool/onebug.pl?bugid=CSCsb72324

Also here is a step by step guide to troubleshoot mwi

There wasn't a LAN outage that I'm aware of and we don't have failover. I appreciate your post, though.

I think I may have found the bug: http://cisco.com/cgi-bin/Support/Bugtool/onebug.pl?bugid=CSCec50802

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?
