I have run into an issue where the EMC, Exchange 2010 Organizational Health and (Get-mailbox -resultsize unlimited).count all return different counts.

For example:

Exchange 2010 Organizational Health 7,392

EMC                                                 7,344

Cmdlet                                             7,490

Which number is the correct number of mailboxes?

Where does the Exchange 2010 Organizational Health pull that number from? The only thing I could find on that is that it uses Set-OrganizationConfig OrganizationSummary.

I verified that there are no filters applied to the Recipient container.

Thanks,

Hi,

Get-Mailbox will only get the list of mailboxes. It won't include a list of archive or arbitration mailboxes. To get these, you need to use the commands below:

(Get-Mailbox -Archive).Count

(Get-Mailbox -Arbitration).Count

Thanks.

Hi,

Organizational Health collects the following data: number of servers, number of mailboxes, server roles and licensing summary. If you look into this file: ExBPA.StayingInformed.Config.xml, you will find where the Exchange 2010 Organizational Health pull that number from. Set-OrganizationConfig OrganizationSummary is for saving Organizational Health Data.

And where do you get the number from EMC? Navigate to Recipient Configuration -> Mailbox, the result should be the same with Get-Mailbox cmdlet. Check the max number of recipients to display. Click refresh button to check the results.

Best Regards.
