What Is Microsoft Teams?
Microsoft Teams is the communication and collaboration hub of the Microsoft Office 365 product family. Teams looks a lot like Slack, and that is very intentional. Slack changed the way teams communicate with each other, and Teams is building on that foundation.
Teams is available for most licenses of Office 365, so you will find it in corporate or business settings, the federal government, and educational institutions.
Teams is a “single pane of glass” where you can hold discussions with your co-workers, have one-on-one conversations over chat, and view and open shared documents. You can start a voice or video call with screen sharing if you need it.
Teams is a solid platform for team collaboration, read on to learn how to take advantage, and still stay secure.
How to Use Microsoft Teams
Before we get into the day to day, there are a few other things you need to know if you are setting up Teams for your organization. Each team you create in Teams creates a SharePoint site, OneNote, and Office 365 group on the backend. You can think of Teams as a front-end to those behind the scenes systems in Office 365. This will also help you understand how to use Teams as that front-end.
- Organization-wide chat, communication, and collaboration platform
- Seamlessly share and edit documents and calendars
- Switch between voice, text, or video communications in the Teams interface
- Connectors allow integrations with Salesforce, SuccessFactors, Zendesk, Mailchimp, Evernote, and more
Each Team has different channels where they can have conversations with the rest of the team.
For example, our Marketing team has a General channel, Budget, Inbound, Not Work, and Reading List. Or those are the ones I choose to display. Users can hide channels that they don’t want to see. You can allow users to create new channels as I did with our “Not Work” channel.
Each channel has a unique conversation history. You can use @mentions to highlight a post for a user, and Teams uses the Windows built-in notification system to pop-up alerts if you want them.
Each channel has several tabs available.
Posts are where you see the conversation, Files is the directory for the SharePoint site, and you can add more as you see fit.
New tabs can turn your Teams into a true central communication hub for your organizations. You can add feeds from SalesForce, SuccessFactors, Zendesk, and of the other 180 integrations available at present.
Files in the Files tab are automatically shared with the rest of your team. Otherwise, the file view is just like any other Windows directory. You can create links to these files in this interface, depending on your organization’s file-sharing rules.
Clicking on this file opens the edit interface in the Teams window, which shows you just how integrated Teams is to the Office 365 ecosystem. You can then open the file in Word.
The Chat option on the left takes you to ad hoc one-on-one or group chats.
From this view, I can chat, call, start a video call or share my desktop. I can also add other people to the chat, and share files between the group of us with the Files tab.
Teams requires that you have a Microsoft account and a license for Office 365. However, Microsoft released guest access to Teams in November 2019. Now Teams users on Enterprise licenses can invite external users to their Teams channels.
You can install Teams on most any device. I use it on my iPhone and work laptop.
For enterprise customers that need to roll out Teams to the entire organization, Microsoft put together guides for you to follow.
How Does Team Collaboration Work?
Teams works basically the same on each platform. These five tabs are key to navigating and seeing your messages and meetings and such.
- Activity: Shows messages from all of your channels. Most recent and unread are at the top and in bold.
- Chat: This tab shows you your one-on-one or smaller group conversations.
- Teams: Here, you see all of the channels you are in, and you can then go to that channel with a click.
- Calendar: If you have the Outlook Calendar integration turned on, you will see your Outlook calendar.
- Calls: This is the voice call history and where you can listen to voicemails.
Benefits and Risks of Microsoft Teams
Of course, a collaboration and sharing platform is going to introduce the increased risk of data breaches. Here is a scenario for you. Your users love Teams – it’s great. They create new cross-functional teams and share documents for collaboration and generally get excellent work done. They invite guests to join channels to discuss work and create sharing links so anyone can access their files when they need them.
On the one hand, easy file sharing and collaboration sounds awesome.
On the other hand – and especially for the security professionals out there – that is an incredible amount of new and chaotic risk that gets introduced into your network.

Varonis rolled out Office 365 and Teams, and we are the most security-conscious company I have worked for. At the core of our data security strategy is monitoring and threat analytics with Varonis. Constant monitoring and oversight of Teams and Office 365 is the best option to make sure there are no active shenanigans afoot on your network. And of course, eliminate stale sharing links and maintain security and visibility to sensitive data at all times.
Microsoft Teams Security Best Practices
Check out these best practices for managing Teams:

- Leverage chatbots to promote daily activity and tasks
- Use PowerShell to manage Teams
File Sharing and Security
- Require multi-factor authentication
- Enforce least privileged access across Teams and Office 365
- Classify sensitive data and use Varonis and Microsoft AIP for additional protection
- Prevent file download to unmanaged devices
- Audit external sharing
Microsoft Teams vs. Slack
Teams biggest direct competition is the other major communications and collaboration platform, Slack. They are very similar in basic functionality. Slack does have a free version that allows users to create their own sites without any cost, but with limited functionality.
I’ve used both, and they both work well. Ultimately, I think the decision will come down to which platform you prefer – Office 365 or not. If you invest in Office 365, you probably won’t use Slack. If you aren’t a full Microsoft shop, then you might investigate other options.
Here are some other highlights for you to consider:
- Slack: Switch between different teams or servers quickly
- Teams: Have to log out before you log into a different team, and you have to use a different account
- Slack: Anyone can join any Slack channel with a free account
- Teams: Guest access is a new feature as of Nov 2019, so we’ll see how it works
- Slack: Over 800 third-party applications integrated
- Teams: Around 180 apps integrated, but total integration with Office 365
While Slack and Teams are the two big players, there are many alternatives. Most of them are niche players that fit a specific gap. Depending on your use case, you might want to investigate those further.

Q: How Do You Use Microsoft Team Meeting?
A: You can either start a private meeting or schedule a Teams meeting from the Calendar tab in Teams. This functionality is replacing the same from Skype for Business. Skype for Business is going end-of-life in 2021 as its functionality is moved into Teams.
I find Teams to be a solid addition to the Microsoft portfolio. I will admit that before I got the updated Office 365 versions of Word, Excel, and PowerPoint installed, there were some annoyances sharing and saving files to OneDrive. The upgrade has resolved most of those issues. It’s easy to share documents and chat with my teammates, and that’s pretty much all I need.
Now, I wouldn’t recommend that you implement Teams without Varonis. The Varonis monitoring, classification, and threat detection is too important to preventing data breaches and keeping your data safe. But don’t just take my word for it, how about a Varonis customer that is implementing Teams and Office 365 right now?
