O365 - Upgrade your IE

I recently came across this vital post from our MVP Tony Redmond on his Exchange Unwashed blog about the IE8 issues with O365 and the most important part to look in to the topic is over IE8 support which ends on 8th April 2014 which is not too long and post this date O365 users will have Outlook Web App Light shown with the IE8 browsers and this is eventually a potential impact to the End user Experience and also for Admin Experience, IE8 is already considered as a Legacy browser and soon Organizations need to plan their IE upgrade to the latest IE11.


Microsoft team has already updated this in the O365 Message Center and the deadline is very near , Let's ensure that we all upgrade our Environment to IE11 at the earliest. Users can still use other Browsers with their latest version to access Web Mail but the recommended process is to use the supported latest Microsoft product to receive proper support experience.

Additionally, Read the latest TechNet post released by Microsoft which talks more on the updated requirements with O365

* Microsoft Team updated O365 customers to upgrade their browser version through Message Center already as shown below.


* Below is the Official Microsoft Knowledge base article on this issue explaining the same and also if you still need your users to use OWA through IE8 then you need to manually set their OWA access to OWA light and revert it post IE upgrade else they will face performance issues as stated clearly.
