While I understand Google had to do a lot behind the scenes to ensure that actions mapped into Gmail properly, it has been a long wait for long-time Gmail users like me to get IMAP support in Google’s mail product. I’ve been using Microsoft Exchange for email for a while, but with my reshuffling of jobs, I found I no longer need the advanced features that it provides. Instead, with the new addition of IMAP access (a necessity in my books), I decided to save myself the money on Exchange and switch to Google Apps, and as such, back into Gmail.

This decision left me with a conundrum – how to get my bank of email out of the clutches of the MS empire and into the supposedly less evil Gmail. While my mailbox is not the largest around, weighing in at around 2GB, this was still a daunting task. IMAP support certainly made this easier, but finding the right application to do the move proved difficult.

I tried Outlook 2007 itself, Mozilla Thunderbird, Entourage, and Eudora with varying success, from Outlook’s constant timeouts on the IMAP connection, to Thunderbird ending up with messages without subjects or senders due to Exchange mangling headers. The solution came from an unlikely source: Windows Mail.

Windows Mail is the replacement to Outlook Express in Windows Vista, and was able to import email directly from the Exchange server through Outlook, then upload it to Gmail through IMAP. While the process was slow (around 10 hours for all my email), it managed to get the job done perfectly, without any timeouts and with the complete messages intact. I did not expect much from Windows Mail, but it pulled through in the end, and if Thunderbird wasn’t so damn good, I would consider using it as my full-time email client.

I now have Thunderbird with the Lightning calendar plugin syncing to my Google Apps Gmail and Google Calender, complete with all my email and calendar entries from Exchange. I still fire up Outlook and use the wonderful RemoteCalendars to pull down my Google Calendar for syncing with my iPhone and other devices, but other than that I am totally satisfied with the free alternative to Exchange.
