How do you ensure that you always have access to all your emails - even at places where there is no Internet or when you aren’t carrying your own laptop?
One of the popular options is that you use a tool like Microsoft Outlook to download all your emails to the computer beforehand and you can then read them anywhere even in offline mode. Both Gmail and Hotmail offer POP3 access to help you download messages using any email client while there are easy workarounds for Yahoo Mail.
There are some downsides though. First, most email clients aren’t portable (can you carry emails on a USB drive?) and second, if all you want is offline access to your Gmail messages and nothing extra, Outlook is probably too heavy a tool for that purpose.
I have been testing a Windows-only utility called MailStore that seems like an ideal solution for such a problem – the tool is free, there’s a portable version for your USB stick and best of all, it works out of the box with your email account without requiring any configuration.
