I am currently working in an Office 365 hybrid environment. I did a Get-Mailbox and Get-MailboxStatistics on my own mailbox and discovered that the value of originatingserver is different for each command.

Does anyone know why?

Is your mailbox hosted on-premises or in O365?
Since Office 365 is running a huge DAG for Exchange things do move around. Also note that multiple servers in the same virtual Exchange organisation in Office 365 could respond for your mailbox.

  • Thanks. Despite the different values of originatingserver, the database names are the same.

The originating server property should be the name of the server that was queried to get the information, it is not a property of the object itself.

In my on-premise Exchange server, it would return DC server name with “Get-mailbox”, while Exchange server name with “Get-MailboxStatistics”.

  • Thanks. When I was working in Exchange On-premise, I didn't bother to check originatingserver because there was only one Exchange Server.
