To be honest, it comes with the general Office365 package and if you are leaned on Azure(popular where I am from), then why not use it as is? Teams is convenient too, as adding a calendar invite means you get am auto generated meeting link. And in most cases business & accounting teams make the choice and implement it company wide as policy. We also use it, but out of frustration, many of our colleagues use Slack as well as some hardcore engineering teams are too reluctant to use Teams and outright use Discord. Many of the teams brought in the issue to upper management about Teams but they redirect us to our IT management company, who tells us it comes with subscription and our business strategists or something has to ask to change this but they want an “ubiquitous” company wide system and so on. Now we are often stuck with messaging people in three different places because someone will never respond in Teams, someone may not be in Slack and someone may not be using discord :)
