What is the role of the Microsoft Exchange Information Store service?
This problem may occur if you use another user's mailbox in Outlook 2002. See ME812007 for more information about this issue.
Some antivirus software requires that you use an Exchange Service Admin account, so it can open and scan all mailboxes. This causes Event ID 1016 to be logged for each mailbox. See "JSI Tip 1789" for details.
As per Microsoft: "This event is logged even if you have been granted permission to access the mailbox, and even when you successfully access the mailbox. However, this event is not logged if a primary Windows NT account is not assigned to the user's mailbox". There are several Microsoft articles with information about this event: ME147362, ME173692, ME239081, ME244305, ME274317, ME280527 and ME301328.
This is a normal event and it will be logged in the Event Log regardless of the level that the diagnostics logging is set to on the Information Store. For example a backup software performing backup at the mailbox level will cause Exchange to generate such events.
