[Version] Printed [Location] Page 109 Inside Out sidebar: Too many objects [Submitted By] Tony Redmond [Date Submitted] Oct 01, 2013 [Description] 
The number of objects returned by EMS is 10,000 not 1,000. The text for the sidebar should be as shown below: By default, EMS returns up to 10,000 objects in response to cmdlets. (The value in Exchange 2007 is 5,000.) Therefore, if you run a cmdlet such as Get-Mailbox, Exchange will return up to 10,000 mailboxes if they are available. If you work in a small Exchange organization that supports fewer than 10,000 mailboxes, you don�t need to worry too much about the number of objects you have to deal with because PowerShell will likely return relatively few objects, and things usually progress quickly. However, it�s a different situation in large organizations, where you have to pay attention to the filters you specify to retrieve data or override the default limit for returned objects by specifying the ResultSize parameter for cmdlets. For example, to let EMS return as many mailboxes as it can find, you could use a command like this: Get-Mailbox �ResultSize Unlimited This command will work, but it will be very slow because EMS has to read every single mailbox in the organization. Think about how long this might take to execute in an organization that supports more than 300,000 mailboxes. In these situations it�s always better to specify a filter to restrict the number of objects EMS looks for and returns.
