Total Mailbox and Attachments Sizes

This resource graphically details the value history of the current performance counter, in this case, the total size of the selected mailbox and its attachments. Hovering over any time period within the chart displays detailed information about that time period in the tooltip.

The colors of the main chart correspond to the labels in the legend. You can choose which data to display by using the check boxes in the legend.

Attachment Size shows the total size of those email messages that include attachments, including the email message body.
For more information, see Mailbox Details.


You can have the chart show a predetermined time period of data by clicking on any one of the three Zoom buttons in the head of the Zoom column. Alternatively, you can have the chart show a specific date range by dragging the mouse over an area of the chart or manipulating the sliders of the lower chart.
