We are rolling out Office 2010 and it is causing some issues, particularly with VB 6.0. One is it seems to unregister, or register a different version, of common controls and VB 6.0 projects don't come up properly. They just need reregistered. Excel automatically saves a back up we don't really want. The default is Excel documents are protected so we needed to adapt to that. Our tech guys installed Office 2010 right along side Office 2007 (left the folders there). If you bring up Access 2007 it causes problems for some mailmerges. Just bringing up 2010 fixes it. There are some more and everything that came up had a solution on the web.

Just a "heads up" that it wasn't seamless for us.
