I am trying to run a report on all incoming mail to a specific mailbox. When I log into ECP and navigate through tomail flow -> delivery reports I don't seem to be able to search all incoming to a specific mailbox. For example, noreply@company.com sent an email to user@company.com - I can log into OWA as user@ and see an email from noreply@.
I can see emails that user@ has sent outbound, but no inbound.
However, when I log into ECP and add "user@" into the 'Mailbox to search' textfield and clicksearch I don't see the email item.
Is there a limitation on what can be searched in ECP, perhaps I need to use PowerShell? Does anyone know the answer to this?
