Users By Mailbox Size

This SAM widget shows metrics concerning mailbox size per user, as monitored by AppInsight for Exchange.

To sort data, click the header of a column. Hover over any user in the User Name list to display details about user's mailbox in a tooltip. Click any database in the Database column to open the Database Details page for that database.

  • If no user mailboxes exist in a given database, this widget does not appear on the Mailbox Database Details page.
  • If no user mailboxes exist in any active databases on an Exchange server, this widget does not appear on the Application Details view.
  • User mailbox information is collected once daily after midnight, local time.

The following list defines each column of this widget:

  • User Name: Name of the listed user.
  • Mailbox Size: Total size of the listed mailbox that is currently being used by the user.
  • % Quota Used: Shows the percentage used of the listed mailbox.

    This value may vary from what is displayed for mailboxes in Exchange because AppInsight for Exchange uses the "Prohibit send and receive" quota as the last point when a user will stop receiving emails, instead of the "Prohibit send" quota, which is a smaller value. To change how quotas are calculated, enable the QuotaUsageAgainstProhibitSend option in Advanced Configuration Settings. Click here for details.

  • Attachment Size: The total size of all emails with attachments. This includes the body of the email, as well as any attachments. For details about which attachments are tracked, see Attachment extensions acknowledged by AppInsight for Exchange.
  • Attachment Count: The number of email messages that contain attachments, as opposed to the actual number of attachments contained in each email.
    Note: The maximum number of email messages with attachments that can be reported is 10,000.
  • Last Accessed: Displays the time and date the listed mailbox was last accessed by the user.
  • Database: This is the database that contains the listed user's mailbox.
