Outlook error "Something unexpected went wrong with this url"

This worked for me...mostly. Instead of getting an error, I get a Microsoft Outlook Security Notice pop-up prompting me whether I want to continue to that location. I'll take it!

Still not a decent solution… It makes users without IT skills feel unsure.

Hi,

The resolution is well describe in the Microsoft documentation and it requires your IT team to deploy an GPO, this is faster is more secure

In order to add the file shares in registry by GPO, consider the following:

If it’s a Domain

For the Contoso example above, it is set in the registry here:
Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains\contoso.com

If it is an IP address, it is set in the registry here:
Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Ranges\Range1

And for each IP address share it is required to create a new Range key under Ranges.

Example of a Domain

Example of an IP:

Have you ever tested this behavior? I'm afraid, but I don't think so.

And nevertheless, when trying to open a link from an email in Outlook, I still encounter a warning message:

This issue is very frustrating!

@honeybee,

Jorge added the solution to the dialog you are seeing in the main article, Outlook blocks opening FQDN and IP address hyperlinks after installing protections for Microsoft Outlook Security Feature Bypass Vulnerability released July 11, 2023 - Microsoft Support. Try this reg key from the article and see if it helps:

When you open links in emails in Outlook Desktop where the path is to either FQDN or IP address or hostname path you will see this dialog. This is also expected. 

If you need to disable this dialog, follow the instructions in the article Enable or disable hyperlink warning messages in Office programs.
