Does MessageStats truly exclude mailboxes? Example: I have 1000 users with a mailbox each. 500 are real, 500 are training accounts that do not need to be reported upon. Is there a way we can make sure that no resources are put towards these 500 training accounts?
Configuring Mailbox Exclusions
You can exclude mailboxes from the gathering process. There might be mailboxes in your enterprise that generate a large volume of e-mail, but you may not want to include these mailboxes as part of your usual e-mail traffic. For example, you may have an infrastructure monitoring application that generates notifications by e-mail. The traffic generated by this application probably should be excluded from your overall analysis of messaging traffic generated by users.
To exclude mailboxes, Quest Message Stats performs a text comparison between the originator and all recipients and the text that you enter in the Mailbox Exclusion Management tab. MessageStats does not recognize aliases or other distinguished names ( DNs) when excluding mailboxes
How Exclusions Affect Reports
Mailbox exclusions do not apply to reports that include structural properties, such as Mailbox Sizes and Mailbox Quotas. These reports include data for all mailboxes, regardless of the exclusion status. If you try to audit a mailbox that appears in the excluded mailbox list, no audit information is available.
If you exclude a mailbox, the following reports do not contain data for those mailboxes:
Mailbox Auditing, Subject Auditing, and Domain Auditing
