Message Center Major Change Update Notification – SharePoint Tenant Opt-Out for Modern Lists is Retiring in 2019

Sent by Microsoft this morning.

We’re making some changes to how environments can opt out of modern lists in SharePoint. Starting April 1, 2019, we’re going to begin retiring the ability to opt out of modern lists at the tenant level.

[How does this impact me?]
In 2016, we introduced a new “modern” experience for SharePoint, bringing extensibility, accessibility, and responsive design to a complete overhaul of the user experience. Since then, modern has been the center of innovation in SharePoint and OneDrive, although classic mode remains supported and available.

We’re making it easier for users to get to our latest feature updates. Starting April 1, 2019, it will no longer be possible to restrict an entire organization (tenant) to classic mode for lists and libraries. Lists and libraries may still use classic mode using the granular opt-out switches that we provide at the site collection, site, list, and library levels. Additionally, lists that use certain features and customizations that are not supported by modern will still be automatically switched to classic mode.

After April 1, lists and libraries that are in classic mode as a result of tenant opt-out will automatically be shifted to modern. Users will benefit from enhancements and new features such as attention views, PowerApps integration, Flow, column formatting, and the filters pane.

[What should I do to prepare for this change?]
The SharePoint Modernization scanner identifies sites and lists that have customizations that are not supported by modern UI. Although many of these lists will automatically remain in classic mode even after this change, you may wish to keep some sites running entirely in classic to avoid users switching between different experience modes within a single site.

Administrators can use a PowerShell script to enable or disable the modern experience for a single site collection or for a list of site collections as provided by the SharePoint Modernization scanner. Alternately, users can still use the “return to classic” option on modern views of lists or libraries to temporary return to classic, and list owners can use List Settings to configure that list to use the classic experience for all users.


  1. I couldn’t agree with you more Jac. They are moving at breakneck speed, taking away things we use every single day, over-complicating the permissions model, and adding stuff that most businesses are simply not ready for. The cloud is a monster I’m afraid and they are not moving anywhere near the pace of their clients. It is a very big challenge, one I’m not sure how we’re going to resolve. I really miss the days of on-premise SharePoint where the platform was stable for 3 years before any major changes happened. It allowed all of business to catch up. Those days are totally over.


  2. When is SharePoint going to let corporation use the product with customisations that suit our businesses alone? Why are we being forced to adopt changes that our companies don’t want or need. Every change made by MS/SharePoint is a huge impact on our groups who have our company projects to deliver, but it seems once you adopt SP you start working for SP continually making changes. OpenText here we come…..
