I would like to produce a report that would list the size of a group of mailboxes/all mailboxes in my organization.


The best solution is to use the Mailbox Storage Information report template. You will find it on the Templates > Storage menu. Information is collected using  PowerShell.

You will apply the following settings:

  • Selection tab: All organization mailboxes.
  • Group tab: No grouping.
  • Filter tab: N/A.
  • Options tab: Sort by, Item size.
  • Content tab: Mailbox Storage (item size and count), see below screenshot.
  • Presentation tab: Display = Table, Size in MB = MegaBytes.
  • Output tab: Your own choice (Screen, Printer, Disk file, Email recipient, Sharepoint, Database table).
