Today’s solutions for corporate communications are more robust than ever and Microsoft remains a top player by continuously innovating the Microsoft Teams video platform. New product features are amazing but can often confuse the end user. Do you know when to use a Teams Live Event vs. Teams Meeting with Overflow vs. Teams Webinar? The Enterprise Video Strategy (EVS) team at Kollective will help you navigate the best solution for your particular use case.

Microsoft Teams Live Events

Teams Live Events are an extension of Teams meetings that allows users to deliver video and other content to large audiences. It’s Microsoft’s primary one-to-many communication tool and is ideal for events where the host needs complete control of the content being presented – like a CEO Town Hall or All Hands Meeting.

In a Teams Live Event, presenters and producers handle sharing audio, video, or their screen with the audience and only one presenter can be active at a time. The audience can interact with presenters via moderated Q&A sessions or in Yammer. Attendees who are unable to watch the event live can view the recording after in Teams, Stream or Yammer.

Another benefit of Teams Live Events is that they fully integrate with enterprise content delivery network (ECDN) technology. An ECDN enables organizations to scale high-quality live and on-demand video behind the corporate firewall by optimizing bandwidth consumption. This is especially important for enterprises and small and medium businesses (SMB) with offices challenged by network capacity, remote locations and/or bandwidth limitations.

What are the Pros and Cons of Microsoft Teams Live Events?


  • Host up to 20,000 attendees through December 31, 2021
  • High production value
  • Equal access of features
  • Full ECDN functionality


  • Limited interactivity
  • Takes some training to understand how to use

When to Use Microsoft Teams Live Events

Teams Live Events remain the gold standard for large-scale, one-to-many communications. Choose to host a Live Event for meetings where audience interactivity is not necessary and executive polish is required.

Microsoft Teams Meetings with Overflow

While typical Teams meetings allow you to host up to 250 participants, Teams Meetings with Overflow expands that, now enabling up to 10,000 attendees to join your meeting. The first 1,000 users that join get to enjoy the same Teams Meeting experience they know and expect: they can share their own audio and video, view shared content, and interact in chat. Attendees that join after the 1,000-user capacity is met enter in view-only mode with reduced interactive capabilities.

View-only attendees cannot take part in chat or view PowerPoint Live files, or files shared using individual application shares. They are also not included in the event analytics, making it difficult to gain full insight into meeting performance.

The only way to know more about your Overflow attendees and their quality of experience is by deploying an ECDN. When used during a Teams Meeting with Overflow, an ECDN scales content and collects analytics for all view-only users.

What are the Pros and Cons of Microsoft Teams Meetings with Overflow?


  • Higher attendance capacity than a standard Teams Meeting
  • Collaborative environment
  • Easiest set up of Teams video solutions


  • No analytics collected on overflow attendees without Kollective ECDN
  • ECDN only scales Overflow viewers
  • Technical limitations

When to Use Microsoft Teams Meetings with Overflow

Microsoft Teams Meetings with Overflow should only be used when you require the same level of interactivity as a standard Teams meeting with over 250 users. If your network does not have the capacity to scale live video to 1,000 employees, opt for a Teams Live Event instead.

Microsoft Teams Webinar

Micrsoft recently released its new Webinar tool for Microsoft Teams. Designed to compete with top virtual event platforms, Teams Webinar offers many of the same benefits, including event registration pages, breakout room configurability and a dashboard that displays attendance data relative to registration details.

Teams Webinar does support ECDN functionality, scaling video for viewers behind the corporate firewall. An ECDN also supplies advanced analytics for all attendees, so you know who, what, where and when your Webinar was consumed.

What are the Pros and Cons of Microsoft Teams for Webinars?


  • Host up to 1,000 attendees
  • Registration page integration
  • Disable/enable cameras and microphones (globally or individually)
  • Configuration of breakout rooms before the meeting
  • Breakout room timers, room retention, and attendee reassignment
  • Dashboard displays registration and attendance data


  • Focused on external customer engagement, not internal use

When to Use Microsoft Teams for Webinars

Microsoft Teams for Webinars is best for meetings where you want a high-level of interactivity and tracking for up to 1,000 attendees. While Webinars can be used internally, it is especially useful for external communications and marketing activities.

Choose the Right Tool for the Task

To determine which option in the Microsoft Teams ecosystem is right for you, consider the purpose of your event and how you want your attendees to engage. For events where a high-level of interactivity is needed, consider Webinars or Teams Meetings with Overflow. However, for one-to-many communications and large-scale internal broadcasts, Teams Live Events will serve you best.
