It's been a month since we had a smooth transition from Google Apps to Windows Live Domains for our email/app needs. The documents / resources we had to refer for the same weren't much comprehensive, so we had to find our own workarounds.

We had to make a hard choice of forfeiting our beloved Google Apps (a) Google Custom Domains account to find a lighter on cost (free) alternative for our emailing needs and primarily being Linux users offered us more problems to solve as the alternative we found suitable is from Microsoft.
