Hello, we are planning to upgrade the clients used by final user : IE 6 and office 2003 to IE 7 and office 2007 in a farm having MS Office SP 2003 installed. Are there any problems/issues about compatibility or bugs using these versions to work in a farm SP having SP 2003 installed? thanks

You should find no difference. Just don't expect that changing from Office 2003 to Office 2007 will give you additional functionality in connection with SPS 2003. It won't. (For full functionality of Office 2007 with SharePoint systems you will need WSS 3.0 or MOSS 2007) P.S. You will probably need to add the latest IFilter Pack in order to have support for Office 2007 formats in your Search functions. 2010 Books: SPF 2010; SPS 2010; SPD 2010; InfoPath 2010; Workflow etc. 2007 Books: WSS 3.0; MOSS 2007; SPD 2007; InfoPath 2007; PerformancePoint; SSRS; Workflow Both lists also include books in French; German; Spanish with even more languages in the 2007 list.
