Collecting Statistics

A Mailbox Collect Statistics Task conducts an assessment of mailboxes of selected accounts in the source tenant and provides the following information:

  • Size of the mailbox
  • Number of items in the mailbox

Each Mailbox Collect Statistics Task generates events. Events are milestones that a task achieves as it runs. For example, when a Mailbox Collect Statistics Task starts, an event is logged and it appears in the events list. When the number of accounts that are selected for assessment is large, the Mailbox Collect Statistics Task divides the total number of accounts into manageable sets. Each set is called a batch. When a batch of accounts is assessed, another event occurs.

The Mailbox Collect Statistics Task and its events provide additional information about the mailbox for the set of source tenant accounts that are assessed.

NOTE: Before you proceed, verify that the source tenant accounts have been discovered. For more information see Discovering Accounts
