Hello - I have a strange issue that has us quite stumped here. The en result is that the Information Store is often turned off at around 7:00AM. I have looked at the event logs and it appears that at 7:00AM this morning there was a series of 1034 messages about stopping several services related to Exchange (IMAP4, POP3, Exchange Transport) and a report that hte service closedown was completed at 7:02AM. Most of the services did restart but not the Information Store which I started when I arrived at 8:00AM.While coming back up there is a log entry stating Event ID: 906 "Information Store (7940) Server unregistered: MS Exchange Server/MS Information Store"I just saw a similar sequence at 10:30AM except that the Information Store came back with the balance of the other services. Has anyone else seen this type of issue?
