Why choose Microsoft Teams or Mattermost?
When it comes to pricing, Microsoft Teams offers an entry-level price of $4/month/user, while Mattermost is more expensive with a price of $10/user/month. Microsoft Teams also offers a free trial of one month, while Mattermost does not. Both platforms offer a free version, but Microsoft Teams offers more add-ons and features such as graphic personalization, contact management, and workspace and user activity tracking. However, Mattermost offers unlimited storage, multiple workspaces, and task management features. Both platforms offer mobile, web, and desktop apps, as well as SAML/SSO authentication and end-to-end encryption. Ultimately, the choice between Microsoft Teams and Mattermost will depend on the specific needs and preferences of the user or organization.
