Outlook on the Web supported browser updates

This initial communication is to notify customers that starting in Fall 2023 (September 2023), users using unsupported bowsers will be redirect to the light version of Outlook on the web. This will align with the experience with other Microsoft 365 web applications (MC518729 February ’23).

When this will happen:

We’ll be gradually rolling this out to Targeted Release customers in early Fall (September), and the roll out will be completed for Standard release by the end of Fall 2023 (November 2023). 

How this will affect your organization:

Once this change rolls out, users in your organization using legacy browsers will be redirected to the light version of Outlook on the web, which only has basic email functions (Learn more about the light version of Outlook).

What you need to do to prepare:

Please check the supported browsers versions and upgrade your organization users’ browsers to make sure they can utilize the full set of features from Outlook on the web.
