Despite a heated rivalry, Slack has announced support for Microsoft Teams calls.

Slack and Microsoft Teams are vying for control of the corporate messaging market. Teams boasts the larger user base, while Slack prides itself on having more engaged users. Both platforms have their unique advantages. Teams benefits from being part of Microsoft’s software ecosystem. Slack, on the other hand, is quickly setting itself apart as the option for companies who compete with Microsoft and are reluctant to rely on the software giant for their communications.

In a move few would have expected, Slack has announced that it now supports Microsoft Teams calls, eliminating one more reason why some users might migrate away from Slack. Now, in organizations where different departments use different options, the newfound interoperability should help ensure Slack doesn’t become an extraneous platform.

As the company’s description highlights, individuals can “bring video conferencing where your team is already working in Slack, from launching a call to joining meetings directly from event reminders.”

This is a good move on Slack’s part and should further solidify its place in the corporate messaging world.
