[German<\/a>]Since installing the July 11, 2023 security updates that closed a Security Feature Bypass vulnerability in Outlook, some users can no longer use hyperlinks without restrictions. Either a warning comes up or the hyperlinks no longer work. Now Microsoft has spoken out and has also suggested a workaround.<\/p>\n

Hyperlinks causes a Outlook warning<\/h2>\n

\"\"I had picked up on July 19, 2023 in the blog post Outlook 2016: Links broken after update from July 11, 2023 (KB5002427) \u2013 Security warning appears when clicking links<\/a>. If users select links to open in Outlook after installing the security updates, a security warning appears.<\/p>\n

Microsoft Outlook Security Notice<\/p>\n

Microsoft Office has identified a potential security concern.
\nThis location may be unsafe.<\/p><\/blockquote>\n

The issue was indeed related to Office 2016 and the KB5002427 security update for Outlook 2016 in the post. However, the flaw also occurs in Outlook from Office 365 when the July 2023 security updates to close the Microsoft Outlook Security Feature Bypass vulnerability CVE-2023-35311<\/a> are installed. Phil had then reached out in this German comment<\/a> and wrote:<\/p>\n

The problem only occurs when the UNC path is used as FQDN. Without domain it works without problems.<\/p>\n

Under Control Panel, Internet Options, Security, Trusted Sites you can enter the FQDN, then it works for us (file:\/\/*.domain.local).<\/p><\/blockquote>\n

This was also confirmed by another user.<\/p>\n

Microsoft confirms the problem<\/h2>\n

Via the colleagues at Bleeping Computer<\/a> I came across the Microsoft support post Outlook blocks opening FQDN and IP address hyperlinks after installing protections for Microsoft Outlook Security Feature Bypass Vulnerability released July 11, 2023<\/a> released July 11, 2023. There the vendor confirms the problem for Outlook for Microsoft 365 and writes:<\/p>\n

When you click on links in emails in Outlook Desktop where the path is to a fully qualified domain name (FQDN) or IP address you may see the following:<\/p>\n

An Outlook warning dialog with the error \"Something unexpected went wrong with this URL\"<\/p>\n
