Slack vs Microsoft Teams: Is the Choice Getting Easier?

Slack vs Microsoft Teams

Comparing Slack vs Microsoft Teams is all the rage right now – but it doesn’t really solve the problem most of us face today. 

Strengths and weaknesses are natural in any product. But, today there are two questions.

  1. What does picking apart these apps achieve?
  2. What is the alternative?

Slack vs Microsoft Teams

As a keen onlooker into Unified Comms and Collaboration, LinkedIn and Twitter have become curated streams of content – especially for Slack vs Microsoft Teams.

Scrolling through, product releases, new user interfaces, and updated features appear daily.

When Microsoft launched the free version of Microsoft Teams, Twitter and LinkedIn have been flooded with comparison articles between the market-leading collaboration apps.

Giving in, and searching Google to get the number of articles out there, you’ll quickly give up. There are loads.

What’s more, the suggested posts underneath lead to even more searches. Searches like Teams vs Slack infographic and Microsoft Teams Slack Reddit are getting so many hits.

Slack vs Microsoft Teams Key Factors


When looking for a meeting solution, typically businesses are already using Skype for Business and Microsoft Teams.

We then see major adoption of Slack’s alternative messaging style meetings. Both very different types of meeting, but who’s to say one is better than the other?

Microsoft Teams has over 329,000 organizations on its books. As of August 2018, Microsoft announced that Teams is now a complete meeting and calling solution.

As businesses migrate from Skype for Business to Microsoft Teams, this number is only going to increase.

Slack doesn’t have a specific meeting feature but is very handy for messaging style meetings.

Slack actively advertise what does and doesn’t work when it comes to meetings. Brainstorming meetings schedule a 30-minute slot and assign the brainstorm to a channel. At the appointed time, have a facilitator prompt the group and let the ideas fly.

With these apps offering different meeting styles, it’s inevitable that you are going to cross over at some point.

What happens when you’re a Slack user and you get a Microsoft Teams meeting invite?

You still have to download the plugin or join online anyway. Comparing Slack vs Microsoft Teams doesn’t really solve the problem of true meeting collaboration today.

Ultimately, these apps are designed to enhance collaboration in business. There is no primary runner in collaboration. Does this help in the battle of Slack vs Microsoft Teams?


Because of the strength and depth of all both vendors, we often see a mixture of both these apps in enterprises.

Requiring a deep set of features is one pre-requisite for Microsoft and Slack. The other is genuinely enhancing the collaboration experience.

Whilst they all do on their own, sometimes it takes a combination of these apps – and then a bunch of third-party integrations too.

NoJitter research from summer 2018 suggested enterprises are best at adopting this mentality.

Larger Equals More
Three or more team collaboration apps are in use in enterprises. The larger the company, the greater the chance of multiple apps in use.

To achieve true collaboration, with Slack and Microsoft Teams, or any combination, there is no catch-all solution.

Even if there was, personal preference would likely get in the way. Forcing collaboration onto users almost always drives failure.

One article by Smartsheet even suggests,

People resent forced collaboration when they aren’t given clear evidence as to why the players make sense. Collaborations that come together naturally are often best because everyone understands what everyone else is bringing to the table.

Comparing Slack vs Microsoft Teams doesn’t really solve the true collaboration problem.

Existing software

Since publishing this post, Agile IT posted an article titled “Why HipChat Users Should Migrate to Microsoft Teams (Instead of Slack).”

Agile IT makes some good points.

For the price of Slack Plus, you can get an entire Office 365 license. A real eye opener for Slack vs Microsoft Teams comparisons.

But, with the increasing popularity of Google’s productivity suite, how relevant is this?

Businesses that have opted for Google and/or Mac are unlikely to see Office 365 as a pro to purchasing Microsoft Teams over Slack.

Integrations are mentioned next. When we compare Slack vs Microsoft Teams, integrations are usually associated with Slack.

Correctly, Agile IT points out there is a huge amount of integrations associated with both platforms.

Another pro for both platforms and no further clarity choosing between Slack vs Microsoft Teams.

However, the negative associated with Slack only hosting ten integrations on the freemium model isn’t that bad either. If you are running the freemium version, you probably don’t need ten integrations. Slack has thought this through.

Whilst the article points to pros and cons for both platforms when moving away from HipChat, comparing Slack vs Microsoft Teams doesn’t really solve the existing software problem.

All in one

Let’s move outside of Slack vs Microsoft Teams for a moment.

Think about the all-in-one solutions you see in other areas of tech.

Take the laptop – an indisputable game changer in the personal computing world. Then ask yourself these questions:

  • Do they work best when they are left alone?
  • Is the experienced enhanced when you plug something else in?
  • Would everyone be productive if they all had the same laptop?

When defining the tools you need to productively conduct a job, it’s easy to opt for an all in one solution.

But, you likely end up with several all-in-one solutions that each does bits of what you were trying to achieve.

Defining what your all in one solution needs to do is part and parcel of collaboration strategy planning. You may have Slack as your all in one messaging app and Microsoft Teams as your all in one communication platform.

According to the Workplace Messaging Report in 2019, 91% of businesses are using more than one messaging app.

Making the list was both Slack and Skype. These are both all in one solutions in their own right. But, ask yourself those three questions again…

  • Do they work best when they are left alone?
  • Is the experienced enhanced when you plug something else in?
  • Would everyone be productive if they all had the same laptop collaboration app?

Comparing Slack vs Microsoft Teams doesn’t really solve the all in one problem.

Messaging is the core

At the heart of these collaboration apps is messaging.

The most common function of Slack and Microsoft Teams is messaging. Be it direct messages on Microsoft Teams or sharing information on a Slack channel, messaging – in one format or the other- is the core.

The good news?

No longer do you need to compare these services for messaging.

You could spend weeks, months or – let’s be realistic – even years trying to work out which platform suits the messaging needs of your business.

You could. But, when developing a messaging strategy, there is a much simpler solution. Just use Mio.

When multiple messaging platforms exist in your organization, Mio can provide messaging interoperability by connecting the platforms of your old and new employees across the platforms of their choice.

This means you can finally stop comparing Slack vs Microsoft Teams.

Stop comparing Slack vs Microsoft Teams and use Mio

Mio is simple to set up:

    I have a couple of questions about MS Teams/Office v #slack/Google Docs that I'm hoping you can answer. I'm used to working in #slack where I can split a thread off from a post in the channel to have a side discussion with one or a few channel members. It appears to me that Teams cannot provide this basic feature. Every pairwise exchange among channel members goes right into the channel, cluttering it with noise. Am I correct in this assessment? If so, I'm incredulous that Microsoft would release such a product. I'm used to working collaboratively on Google Docs where I can @mention someone in a comment in a Google Doc and that comment can become a mini-dialog between myself and the @mentioned person. When I try to do such a thing in an Office doc thats posted to a Teams channel, that comment is posted to the entire channel as well as every response to that comment. Again, if that's how it works, I'm incredulous. Am I missing something?
