em Client

Background

A little over a month ago, I needed to research some past email correspondences.

I am not that satisfied with Microsoft’s Outlook web site.

I find it to be slow and its performance is uneven.

It might be the advertisement, might be that I keep too much emails in my inbox, or the HTML/JavaScript client.

I have a reasonably fast Internet Connection at work and at home and so it is not network throughput.

Save a dozen other posts for Outlook.com.

 

Windows Live Mail

Thought back to yesteryear, downloaded Windows Live and stubbornly installed Windows Live Mail.

Stubborn is the active word here.

My struggles is acknowledged here.

Help

The only good that comes from been stubborn is that a few people let in that they were just as stubborn.

And, that if you really want an email client for your desktop, em-client is a tool that one should shortlist.
