Windows Office OneNote Blocked to Open 120 File Type from Page

2024-04-12 09:45
 
In April 2023, OneNote v2304 officially made important changes to the way attachments with dangerous extensions are opened.
 
Previously, OneNote showed users a dialog warning them that opening attachments could harm their computer and data. But users could still open the embedded file with the dangerous extension by choosing OK in the dialog.
 
With this important change, OneNote blocks users from directly opening an embedded file with a dangerous extension and instead shows them the following dialog.
 

Your administrator has blocked your ability to open this file type in OneNote

Your administrator has blocked your ability to open this file type in OneNote


This strategy will be added in version 2304 in April 2023.
