Although many organizations have already migrated their email to the cloud, some organizations are still looking to make the change. And many organizations that have migrated to a specific solution are now considering migrating to another one.
One of the first questions nonprofits ask when considering cloud hosting is Office 365 vs. Google Apps. Which one should we use?
There is, obviously, no simple answer. At the same time, the consultant’s canard, “It depends” is not particularly helpful. I’ve put together a few resources and also offer my own opinion below.
The Community IT View
Many comparisons of the two services pay a lot of attention to price, but for qualified non-profit organizations the price question is removed because both services are available at very little cost.
In a feature by feature comparison, the two services appear fairly equal, though anyone familiar with both services wouldn’t for a moment get the two confused. Their feature sets match, but they are not the same.
The choice between the two is really a choice of ecosystems:

We have clients who use Office 365 and we have clients who use Google Apps. Both are great alternatives to on-premise messaging and file sharing/collaboration solutions. Both services are very generous with non-profit customers.
