Google’s mail service can use through your Web browser, and when you can’t have the Internet, you can’t access your mails either new or old. This is the same case with other public mail services as well, like Yahoo and Hotmail, but Google recently unveiled a new option for offline mail access.
This is a plugin known as Gmail Offline, this browser plug-in allows users to read, reply, and search mails even when there’s no Internet connection. It has a nice-looking, easy interface that’s almost similar to what you typically see in Gmail but with fewer options.
For the time being Gmail Offline is available only for Google Chrome. Good news is that, similar plug-ins are introduced for Google Docs and Google Calendar.
There is an another option, which can solve the offline problem for not just Gmail, but also Hotmail and Yahoo Mail Plus, i. e. an e-mail client like Windows Live Mail 2011 or Mozilla Thunderbird 6. These programs can be configured to download e-mail and store it locally, thus allowing you to read, respond, and use search; just like with Gmail Offline. One thing you have to make sure that you choose a POP3 configuration and not IMAP, as the latter requires an Internet connection for many functions.
