Microsoft has already been on a roll introducing other features like <a href="https://www.techradar.com/pro/security/microsoft-teams-is-finally-boosting-security-controls-to-let-admins-block-custom-file-extensions">file extension blocking</a>.</p><p>And the problem is very real – in a July 2026 <a href="https://www.microsoft.com/en-us/security/blog/2026/07/23/email-threat-landscape-q2-2026-trends-and-insights/" target="_blank">report</a>, Microsoft revealed a near 10x increase in weekly malicious Teams voice call attempts in just one year, and an 80% increase in voice phishing attempts.</p><p>Still, meaningful progress has been achieved and the company managed to cut phishing activity related to Tycoon2FA, a major phishing-as-a-service platform, by 92% in a year. Looking ahead, the company's roadmap is full of plenty of other Teams announcements, split into some new features and plenty more security updates.</p><figure class="van-image-figure pull-right inline-layout" data-bordeaux-image-check ><div class='image-full-width-wrapper'><div class='image-widthsetter' style="max-width:676px;"><p class="vanilla-image-block" style="padding-top:31.51%;"><img id="diM9tpwF2Lz85R8q85CT78" name="tr-g_news" alt="Google logo on a black background next to text reading 'Click to follow TechRadar'" src="https://cdn.mos.cms.futurecdn.net/diM9tpwF2Lz85R8q85CT78-1920-80.jpg" mos="" align="right" fullscreen="" width="676" height="213" attribution="" endorsement="" class="pull-rightinline"></p></div></div></figure> </article> ]]>
