how to set the default email account in Outlook using PRF file

Hi,

I’m using a PRF file to configure outlook clients when a user logs in.

We are adding an Exchange email account and a pop3 email account to the profile.

By default the Exchange account is always set to be the default email account.

Does anyone know if there is a way I can configure the PRF file so that the Pop3 account is set as default rather than the Exchange?

Thanks

Adrian
