Dear Ama'h
Thanks for choosing Microsoft Community.
Based on your description, I know your requirement. I understand that you are experiencing an issue with inserting network links in the "New" version of Outlook. I apologize for the inconvenience this has caused you.
Regarding your concern, I would like to inform you that this is a known issue with the "New" version of Outlook. Currently, there is no way to override this behavior. However, our development team is aware of this issue and is working on a fix.
In the meantime, you can use the older version of Outlook or use a workaround by copying and pasting the network link into the body of the email instead of using the "Insert Link" option.
I know sometimes it is really inconvenient for users. I can understand your mood. Thanks for bring this to Microsoft Community. Since I think your idea is really constructive. I will report this to Microsoft as soon as possible. Meanwhile, I sincerely suggest you post this precious suggestion to Microsoft. Microsoft will update their product based on customers' suggestions. Believe your suggestion will help many other people in the future. Your understanding and co-operation are highly appreciated.

Thanks for your precious time. Have a nice day.
Sincerely,
Katherine
