> project creating an app in Excel using VBA Oh yeah, this is generally where I'd say things start to fall over. A development platform, it ain't. Generally my advice around VBA is that if you're at the stage you need anything but the simplest VBA, you probably want something else (Access for DB style work or Python/R for data munging). Outlook has got much better - most of the previous issues around lockups and poor performance have improved if not gone away entirely. Can't speak for Exchange.
