This morning I came across this post in the SharePoint 2010 forums. Although it’s nothing critical, it’s good to know the workaround!
This is a known and personally experienced issue (Tech Preview and Beta Builds as well) with Datasheet View not working in SharePoint if you have Office 2010×64 clients installed on your workstation.
Again this is one of the FAQ on the MSDN Forums and today I saw the solution posted on the thread, so comes this post for my reference and in case you experience this, then you know what is the solution to the issue.
Joel Oleson has authored SharePoint 2010: Best Practices for Upgrading and Migrating book and is offering 45 day online access to this book for anyone and everyone!
That’s very generous of Joel and I would like to thank him for this!
I have just signed up online and now have access to this book.
