A week after, Google released Google Message Continuity service powered by Postini to Exchange 2007 and Exchange 2003 customers. Microsoft's telling companies still running Exchange 2010's precursors that they should carefully consider the implications of embracing GMC.
Julie White, director of Microsoft Exchange product management is revealing that,
"GMC doesn't provide a seamless transition for users in the eventuality of an Exchange server outage. Indeed, customers that opt search giant's to backup mail in the Google Cloud will require separate Gmail accounts in order to access their messages.
"This introduces a very different user experience and doesn't support features like Outlook folders. Additionally, Google requires a different password provided by the Exchange administrator.
"In the event of a failure, the user will need to switch from Outlook to a new Gmail account and log in with the new password. In looking at the three options, Google's introduces the most user disruption," she explains.
White also notes that adopting GMC implies that customers will increase complexity across their infrastructure. "In the Google offering, a separate Google Sync Server is required to connect Gmail to Exchange. Additionally, any customer of GMC must switch to Google's anti-virus and anti-spam product," she said.
