No, but that's only because I hate Excel. But I'm sure developers who don't hate it but also appreciate FOSS solutions might be interested, if the pay is good.
Access = LibreOffice Base
Visio = LibreOffice Impress
Outlook = Schleswig-Holstein already switched successfully to Open-Xchange and Thunderbird, I've not heard of them running into any major issues with this setup.
And if the cost of (re)developing all the existing solutions exceeds the costs of MS licensing for a decade?
