I have a client that is using a Blackberry with a Hosted Exchange account using BES from MicrosoftOnline. He also has two Google Apps accounts that are configured through BIS as IMAP accounts.
When Appointment/Meeting request are sent to either of the GMail IMAP accounts, he cannot accept or decline the invitations.
Is there a way to have the device default to all meeting invitations to sync to the calendar associated with the BES account, so all meetings will show in Outlook?

Thanks for your assistance.
