List Inactive Mailboxes on Exchange 2007/2010/2013.

  • Article

Objective:

The script to get list of inactive mailboxes. Inactive is very relative term. For Example, some organizations mark the mailbox as inactive, if it is not accessed for a long time. Other organizations mark the mailbox as inactive, if the user did not sent email for a long period. If you ask me, why they should go by sent item. Some of the reasons could be, the mailboxes are scanned by AV/management tool that changes logon date. So they cannot go by access date. The script identify the inactive mailboxes based on Sent Items.
