In case the Advanced Outlook.com security for Microsoft 365 subscribers is turned on, many links are changed to be in the form of https://eur01.safelinks.protection.outlook.com/?url=https.... instead of the original link.
This add-on undos that process so that the original link is instead used in the message. It decodes the rewritten URL and inserts the original URL instead.
