I have a client who would like a shared calendar/contacts/notes setup in their business. Clients in the office use Thunderbird for their email solution with external hosted email. Clients on the road are using the new iPad. I need to find a solution that is compatible so they can all share a calendar, contacts, and notes and they can all be synced up together.
Does anyone have any suggestions? I was thinking either using some sort of Thunderbird add-in or switch to an email service that supports Exchange and using that. Or even maybe a third party service that offers this that could incorporate into the setup we currently have.
