Outlook error "Something unexpected went wrong with this url"

TO funny how do you have 400 users do that fix. Most user know there way around TikTok and there phones better than there work machines.

The fix can be deployed via Group Policy

GPO: User Configuration

Policy: \Windows Components\Internet Explorer\Internet Control Panel\Security Page\Site to Zone Assignment List

Registry keys can also be prepared and distributed.

I used group policy to add our FQDN for DFS to trusted sites which resolved the link issue in Outlook. However, clicking the link now generates 2 security warnings:

I was able to resolve the first warning message with the following registry edit but I cannot figure out how to suppress the second warning message.

[HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Common\Security]

"DisableHyperlinkWarning"=dword:00000001

Before this link issue was introduced by Microsoft, users could click on any link pointing to a network file and the file would open automatically without any prompting. Any ideas how to disable the "Opening Mail Attachment" warning in Outlook?

Hi Fenrir,

do you use DFS file shares ? , we use DFS , so not specific server IP as such

thanks

Hi,

We've recently encountered the problem and are attempting to resolve it. I was able to find a temporary solution by changing the IP address to the server name instead, and everything is now good. If you're using a login script, you may need to update the server name as well.

I'm hoping for a fix patch as soon as feasible.

Thanks.

We tried o365 quick repair and choose outlook pre mode.

After that we can turn on file link in outlook temporary.

You're right Matt. It's on file path URL's that are having an issue. I suspected that problem was came from recent updates by Windows Update - Security Updates for Microsoft Outlook (KB5002427)

Tried to uninstall the patch and hyperlinks works again. But today the patched (KB5002427) came back and the problem occurred again.

For what it's worth, this KB doesn't seem to be present on one of our machines that's been having the issue, so I don't think this is it.

Also, it's not just 2305 and 2306. We switched the affected user to the Semi-annual Enterprise channel which bumped him down to 2302, and the problem persisted there.

Admittedly, our situation is a little different, as we're using an IP address, not a friendly name, so it's hard to say for sure, but it was working with no issues up until this morning when we had two users report the problem.

What we found was that when we right-click 'Copy Hyperlink', and paste the link anywhere, the URL shows \(IPADDRESS)****path\to\file.csv. It seems to be adding a '' to the path. When we paste it into a web browser, the web browser is smart enough to interpret it and get us to where we need to go. The file browser is not. Notably, this '' is not present in the error itself, and doesn't show as part of the link until you copy and paste it. I'm not sure if it's related, but that seems to be why the link is so picky about where you use it after you copy it.
