By default, does get-logonstatistics return logon stat in past X days? I query some light users that haven't logon for a few weeks and the command returned null, wonder what exactly that means? Is there a way to query the last logon time from weeks or months ago? thanks

Hi, Users who log on to their mailboxes using Microsoft Office Outlook Web App aren't continually connected to the Mailbox server. An Outlook Web App client connects to the server, performs tasks, and then disconnects from the server. Therefore, you may see few or no logon statistics for Outlook Web App, even if users are logged on with this client.Regards from www.windowsadmin.info | www.blog.windowsadmin.info

Would this work for your objective? Get-MailboxStatistics | ft DisplayName,LastLogonTime EDIT: I wasn't able to access an Exchange server when I first posted this but having double-checked: 1) "format-table" or "ft" will probably produce a more readable output. 2) At least on my Exchange production server - E2K7 - the command above shows last logons that took place months ago.
