New Feature: SharePoint File Delete Lockout Override
After feedback from UserVoice and other sources, Microsoft is introducing the ability for a user to delete a file that is currently locked.  This document could be open in another tab or on a different computer, or because someone else had it open and forgot about it.
This feature allows you to override that lock and delete an Office file (such as Word, Excel, or PowerPoint) when you or someone else has it open, whether intentionally or not. The new functionality will be available to people who want to delete items from their own OneDrive, and to all members of a document library who already have permission to delete files.
People who try to delete a file that is open in another location will see a message asking them if they are sure they want to delete the file even though someone else may be editing the file.

They may then proceed with the delete action or close the message and allow other users to continue editing uninterrupted.
Here is an example of the error banner in Word:

People who are actively editing a file when someone else deletes it will see a message explaining that they no longer have access to the file, and in some cases, advising them to save a copy of the document so that work isn’t lost.
This feature will be gradually rolling out to Targeted Release customers in early April with the roll-out schedule to be complete by the end of April.

Microsoft is giving users a way to create a SharePoint list by importing an Excel table
