Unable to download add-in and tools which require validation to MS Outlook which could be used in Office 2000 and Office 2003. Made a large investment in the software and I'm very satisfied with the products I have. I have no desire to go to 2007 and the cost from upgrading is too high, not enough new functionallity in the new software and must learn new interface..
My work decided to remain with 2003 due the large investment and lack of true functionality with 2007. Initial use of 2007 would create an initial loss of productivity.
