Hi, You need to specify an useridentity or create a test mailbox - see http://technet.microsoft.com/en-us/library/dd979787.aspx Leif

Hi djjsin, Did you configure the federation well with other partners? About federation, you could refer to below: http://technet.microsoft.com/en-us/library/dd351109.aspx And then, please check whether you have the defaulttestmailbox, like above reply link referred. If you just configured the two Trusted Forests and wanted to share F/B between them. Then you could follow below: Configure the Availability Service for Cross-Forest Topologies http://technet.microsoft.com/en-us/library/bb125182.aspx Regards!
