One glaring ommission about creating the MSP file after running "Setup.exe /admin" is that once you create the resulting .MSP file, you save it to the "Updates" subfolder of the network installation point, and any MSP files contained within that folder are automatically applied when Setup.exe is run (including the customisations you've made).

To suppress the "Outlook is not currently your default mail application" message at first run of Outlook, configure the "Make Outlook the default program for E-mail, Contacts, and Calender" setting in the OCT. This setting can be found under Modify user settings>Microsoft Outlook>Outlook Options>Other.

setup.exe /adminfile office2010.msp
