After checking out my T-Mobile G1 review and reading how I was looking for a way to get my Exchange information on my device, Clay sent me an email with a link to the press release announcing MailShadow for Google Apps or MailShadowG. I have been using the free Google Calendar Sync tool to keep my Outlook/Exchange account calendar and Google Calendar synced up, but it would be nice to have full email, contacts, and calendar synchronization capability.
Make sure to read the user's guide since there are specific instructions regarding ports that must be open and setup of your Gmail account (IMAP forward must be enabled). You will also need to check with your IT department to get the settings on your server up and running. I signed up and installed the conduit, but have to check with my IT department to see if I can use it at work. You won't see anything different on your G1 since this tool is just syncing your Outlook/Exchange data to Google and then of course your Google info syncs to your G1.
You can sign up for a free 15-day trial of MailShadowG. If you want to continue using MailShadowG then you may want to take advantage of their special introductory price of US$29.95 for a 1 year subscription (offer ends 30 November). The regular price is US$49.95 per year.
