vowe dot net :: Taking SharePoint offline: "Access shares something with Notes: an MDB, much like a Notes NSF, contains a full application with data and UI and code. So this is how Microsoft wants to make SharePoint available offline. It's not Groove, it's Access."
Interesting that venerable Microsoft Access is getting more attention these days, but there's a multi-part answer to Microsoft's plans for taking SharePoint content and apps off-line -- depending on your needs, the answer may include Outlook 12, Groove, and/or Access 12. Microsoft will need to make the selection criteria very clear by the time Office 12 is released.
