We don't scan the exchsrvr dir. The address varies for several users, and as far as I can tell there's nothing special abouth them. Checked technet but couldn't find anything.
Any ideas is appreciated.

Do you have any CDO based applications in the environment? Blackberry or goolink for example? A custom application?

This isn't caused by normal client access, it's an application; probably running under a service account. Find the application and check the account.
