Businesses today are composed of teams that work online and need central hubs for collaboration and communication. Online platforms satisfy that need, enabling people to work together no matter where they are in the world. In 2017, Smartsheet interviewed 1,000 IT decision-makers at businesses across North America and found that collaboration apps are no longer “just nice to have”, but are a necessity in order for businesses to compete. If you have been shopping around and aren’t sure which platform is best for your company’s needs, this blog will compare two industry-leading options, Mattermost vs. Microsoft Teams.

Now you know the basics of Mattermost, so let’s take a look at Microsoft Teams.

Microsoft Teams

Microsoft Teams aims to enable intelligent communications in Office 365 by bringing conversations, files, meetings, Office apps, and third-party integrations together in one place. It is built on Microsoft technologies, powered by the Microsoft cloud, and woven together by Office 365 Groups.

If you’re not a fan of Office 365 for your business, Teams won’t be a good fit as it requires one of the following Office 365 subscriptions:

  • Small Business Plans: Office 365 Business Essentials, Office 365 Business Premium
  • Enterprise Plans: Office 365 Enterprise E1, Office 365 Enterprise E3, Office 365 Enterprise E4 (retired), and Office 365 Enterprise E4 (retired)
  • Education Plans: Office 365 Education, Office 365 Education Plus, and Office 365 Education E3 (retired)

However, you can try Microsoft Teams with a free trial of Office 365.

Here is a look at its features.


  • Collaborate in real-time through chat, voice calls, and video conferencing
  • Share files and collaborate on shared deliverables
  • Connect tools in the workspace like GitHub, Planner, etc.
  • Share data and insights from the Microsoft Graph
  • Invite anyone with an email account as a guest
  • Manage users and guests
  • Schedule meetings using the Outlook calendar integration
  • Use connectors, bots, and tabs to extend capabilities with Teams
  • Hold meetings on a desktop, mobile device, or via Skype Room Systems with HD video.
  • Available in 39 languages

Pros and cons

Next, let’s look at the pros and cons.

Microsoft Teams pros

  • Provides a central hub for communication and collaboration within Office 365
  • Integrates other Microsoft applications and services
  • Video and audio conferencing
  • Enterprise security and compliance
  • Can invite any person with an email address as a guest
  • Multi-language

Microsoft Teams cons

  • Only works in collaboration with Office 365
  • Maximum of 300 users
  • Lack customization and scalability
  • Data is stored with Microsoft

Mattermost vs. Microsoft Teams: Which is better for your business?

The best platform for your business is…drumroll….going to depend on your business.

First, Microsoft Teams is the central hub within Office 365. It brings users together while integrating Microsoft apps and services to create a rich collaborative environment. Being so, it could be a great fit if your company has 300 or fewer users and if you’re already using Microsoft Office apps and services(Outlook, Skype, SharePoint, Exchange, Word, Excel, etc.).

However, if your organization doesn’t subscribe to Office 365 and doesn’t want to, Teams isn’t going to work out. Beyond that, Mattermost offers much more flexibility and security. You can access the source code, drivers, open source integrations, APIs, and more, enabling you to customize the platform to your specific needs. See the Uber case study for a great example of what is possible.

Further, the fact that you can run Mattermost within your own security parameters on a private cloud, provides a higher level of security and control. All of your data will truly be yours and you will never be paywalled from it. Although Microsoft Teams states they do not use or share your information for any purpose, it is still vulnerable to their security parameters and policies. Mattermost removes that risk.

The bottom line

In conclusion, if your company already uses Microsoft Office 365 in daily activities and you are okay with the out-of-the-box platform Microsoft has created, Teams will likely work well for you. On the other hand, if you are looking for a customizable, highly secure, scalable solution, Mattermost is a better fit.
