Microsoft released “10 Reasons Why Enterprise Shouldn’t Use Google Apps.” Coincidentally, on the same day, Zimbra also denounced Google Apps’ enterprise viability. Both of these announcements come on the heels of CapGemini’s recent initiative to deploy and support Google Apps into Enterprise’s worldwide. So, it’s not surprising that Google’s top two competitors in the enterprise office 2.0 space have been quick to react to Google’s widely speculated and inevitable enterprise office suite. Google Presentations are expected to be released this quarter to completely mirror Microsoft’s established office suite. The two main questions to Google’s domination efforts are whether the switching costs away from MS Office are still too high and whether large enterprises will sign-up for office software as a service. Not to mention, the fear that Google Apps’ data is stored on Google’s servers which contradicts one of Corporate America’s biggest concerns/pet peeves–Sarbanes-Oxley (SOX) compliance.
