Since the stay-at-home order started around the globe, demand for videoconferencing has skyrocketed. Facebook even introduced a new video service for its users. What has caught my interest, though, is the battle between Zoom and Teams by Microsoft. Zoom stock has surged significantly for the past two months, especially after it reported that it had 300 million daily active users. Or so we thought
Zoom has confused the comparisons, though. Zoom originally stated it had “more than 300 million daily users” and that “more than 300 million people around the world are using Zoom during this challenging time.” Zoom later quietly deleted these references from its blog post, and it now only claims “300 million daily Zoom meeting participants.”
The differences are important, as is Zoom’s transparency around them. Daily meeting participants counts multiple meetings, so if you have five Zoom or Teams meetings in a day, then you’re counted five times. Zoom has not yet revealed exact daily active user counts, and it looks like Microsoft could be a lot closer to Zoom usage than many had assumed.

For comparison, Microsoft announced today that it reached 200 million daily meeting participants in April. Since the two use the same label, does that mean Zoom has taken Teams’ lunch? Not quite there yet.
The daily meeting participant count can be misleading. For example, Teams doesn’t have a limit on call duration, to the best of my knowledge, while Zoom puts a 40-minute limit on calls that involve more than three participants. So if the participants are willing to set up another call after the free 40 minutes expires, it will bloat up the daily meeting participant count, even though it’s still one meeting that has the same folks involved.
Daily usage can be misleading as well. For instance, I use Jabber at work and it is powered up automatically on my work station. If I don’t interact with anyone on the app, does it mean I am among the daily users still? To be fair, the two companies don’t elaborate on this, but there is one comment from a Microsoft executive
It’s been phenomenal, if I’m honest with you. Let me just start with the DAU thing because there’s a lot of needling on this and we define the DAU. Daily active user for us is the maximum number of users who take an intentional action over a 24-hour period. That’s really important for me to hit. What we call passive actions do not count. So auto boot does not count. Minimizing a window does not count. Closing the app does not count. We also got a lot of questions about that. Skype does not count. So when we release our numbers, we just don’t feel like we want to get in the weeds of kind of argue with people, but the DAU very real.

Another reason is the mix of added users/usage. In its latest investor call in March, Zoom’s CFO commented the following
Granted, there may have been more development since the comment. Frankly, it’s unclear how the surge in usage benefits Zoom financially without the company’s disclosure. Nonetheless, it’s not surprising that the majority of the increased usage comes from the free tier.
On Teams side, it’s not particularly providing a clearer picture either. Back in January, during the Q2 earnings call, Microsoft announced they had 20 million daily active users. 3 months later, the figure stands at 75 million. Quite an achievement. But like Zoom, Microsoft has a free tier that allows video or calls. As a result, barring a comment from the Seattle-based company, it’s not clear how many Microsoft added as paying customers.

The point is that it’s really hard to determine which videoconferencing tool is the better performer between the two leaders Zoom and Teams. The way data is reported by the two companies makes it really challenging to have an apple-to-apple comparison.
