No MWI after subscriber migration

CCM 3.2(2c)

Unity 3.15

TSP 6.02(b)

Unified Messaging

We built a unity server that was running E2K for 20 users. The server was acting as both a Unity server and an Information store for outlook users. Recently they build a seperate E2K to seperate the Unity Voice mail server from the server tht will be hosting information store data.

Before migrating the users over to the new E2K server, We shut down the Unity services. Then moved the users mailbox from the Unity server to the new E2K server.

We started the Unity services back up, however, after this MWI does not work for all users that were migrated over to the new E2K server.

Re: No MWI after subscriber migration

If the AvMsgStoreMonitorSvr service is restarted, do the MWIs for those users still not work? What account is running that service?

Re: No MWI after subscriber migration

MWI's stopped working for all users because they have all been moved over to the new Exchange server.

The Local System account is configured to run the services.

Re: No MWI after subscriber migration

There's probably an issue with that LocalSystem account authenticating with the remote Exchange server. In some instances, NTLM authentication is going to be used. When that happens on Win2K, the machine account (used due to LocalSystem) comes across as Anonymous and doesn't have squat for permissions.

You'll be able to tell if this is the case by turning on ExchangeMonitor trace 10 "component" (I've yet to figure out why we picked this flag), and restart the AvMsgStoreMonitorSvr. As the mailboxes are logged on for notification, if there is an authentication issue, you'll see MAPI failures showing up in the AvMsgStoreMonitor log.

If those errors do show up, you could try downloading the 4.02 version the PermissionsWizard.exe (it'll run fine on a 3.1.5 system). That wizard will ask for the Directory, Messaging and install accounts. Since everything else is working fine, we only really need an account for the Messaging service. That'll be the Domain account that the AvMsgStoreMonitorSvr will use.

Does that make sense? Let me know if it doesn't.
