Zoom is a newer platform and Teams is an app from an established company.
Zoom is a much newer company while Microsoft has been around for long time. Because Zoom is a newer organization within the past year of 2020, the platform did see some issues that a newer company is more likely to experience, such as cyber breaches. People began joining private calls who were not allowed. This issue was eventually resolved, but it leaves a little hesitancy in whether Zoom has discovered all its problematic holes in the system.
What is Microsoft Teams?
Out with the old and in with the new! This upcoming July will be the end of Skype for Business. Skype is a managed communication tool that was first released in 2003. First owned by eBay and later bought by Microsoft it has had a long life, but as Microsoft began creating a more advanced and integrated communication platform, Microsoft Teams, they began to move away from Skype for Business. As of September 1st, all new Outlook365 members will be directed towards Microsoft Teams.
