Google and its Apps resellers and integrators are the first to say that the ideal scenario for Google Apps' deployments is to use the Gmail front end. Blair Collins, founder of InterlockIT.com, a Google Apps reseller and integrator in Toronto, generally tries to steer clients to use the Gmail Web interface, arguing that it will work better and save them money.
"If you're going to stick with Outlook for the long term, it's going to greatly reduce the return on investment and cost-savings of moving to Google Apps," Collins said. In his experience, sometimes problems lie neither with the Outlook sync tool nor with Apps, but rather with Outlook software that organizations have failed to upgrade and patch, he said.
Collins has also seen the Outlook sync tool sputter due to slow Internet connections, a common scenario in small businesses. "When you install Apps Sync for Outlook, it's very demanding on that Internet line because the server is now in the cloud, not sitting in your office any more," he said.
"There is so much more in Gmail that accelerates your business and makes it to much easier to consume and respond to email, that we prefer people use Gmail Web interface," Google's Vander Mey said.
