M365 Changelog: Content Type Deletion – Improved Error Messages

MC399863 – Microsoft will be gradually adding improved messaging when users will attempt to delete multiple Content types from the content type hub or site-level content type gallery in SharePoint.

This message is associated with Microsoft 365 Roadmap ID 93379

When this will happen:

Targeted Release: Rollout is expected to start in end-July and complete by early-August 2022.

Standard Release: Rollout is expected to start in mid-August and complete by end-August 2022.

How this will affect your organization:

SharePoint users will now be able to see the set of dependent lists/libraries if any when they attempt to delete content types from content type hub/ content type gallery and/or site-level content type gallery. Users can then take appropriate action on dependencies and re-attempt deleting content type or re-consider the delete operation based on the dependencies

Users can click on the lists/library links to visit the specific library and take appropriate action.

What you need to do to prepare:

This does not change/add any new flow to the existing delete operation. Microsoft will provide more additional information in case the delete operation fails for content types.

You may want to add this to any documentation or user training and share this with users with relevant permission and who are familiar with using custom content types in your organization.
