Compare office 365 plans - Office 365 E1 Vs E3

You'd think Microsft already must have published the differences between all their subscriptions clearly, but at the time of writing this article, it hasn't. Period. At least there aren't many resources which clearly tell what's the difference!

So, as simple as it may sound, it's not that easy to find a reliable comparison of Office 365 E1 plan Vs Office 365 E3. A log of people want to save on licensing cost by replacing some E3 licenses with E1 but they do not know what features will they miss while doing that. So, I decided to write this article. Hopefully, you will find it helpful.

E3 gives you a bigger mailbox, unlimited archive, litigation hold, unlimited OneDrive etc. It has some other features too which are not available in E1 mentioned below. For E3 users using Office ProPlus today, you can apply S1 (i.e. E3 + ProPlus). This will put some limits on the mailbox, OneDrive etc. based on the E1 plan and remove access to E3-only features which are not available in E1.
