February 19, 2011 was the day I completed a year of migration from MS Outlook to Thunderbird. While I continue to remain an ardent fan of MS Outlook, that does not mean I am against Thunderbird. They have their own pros and cons with the cost going against MS Outlook.
Let me admit it was not an easy transition but I set the ball rolling in office by migrating and gradually others followed suit or was it that they were forced to follow…. There are still features that you do not find in Thunderbird but then I have survived without them so am now all set for Thunderbird. Post the migration out from MS Outlook, I took the plunge and moved out of Windows to Ubuntu and Open Office. Again this transition had its fair share of challenges but team members were receptive to this move and so we have ported quite a lot of desktops onto Ubuntu.
