FAQs
Which should I use, Slack or Microsoft Teams?
The choice depends on your business needs. Use Microsoft Teams if your organization already uses Microsoft 365 and needs built-in video conferencing and enterprise-level security. Choose Slack if your team prefers a cleaner interface, faster onboarding, and broad third-party app integrations.
How do Slack’s Microsoft integrations compare to Teams?
Slack integrates with Microsoft apps like Outlook, OneDrive, and Teams through third-party connectors, but the integration isn’t as seamless. MS Teams, being a native Microsoft product, offers deep, real-time collaboration across Word, Excel, Outlook, and SharePoint, making it a better choice for Microsoft-centric businesses.
Is Slack better than Microsoft 365?
Slack and Microsoft 365 serve different purposes. Slack is a communication tool, while Microsoft 365 is a comprehensive productivity suite that includes Teams, Office apps, cloud storage, and more. If you need just messaging, Slack works well; for full collaboration and productivity, Microsoft 365 offers more.
Is Slack cheaper than Microsoft Teams?
Slack’s free version is feature-limited but good for small teams. Paid plans start at $7.25/user/month. MS Teams is included with Microsoft 365, which starts at $6.00/user/month, offering more value if you’re already using Office tools. So, Slack can be more expensive depending on your existing software stack.
Should a business choose Teams or Slack?
Businesses should choose MS Teams if they prioritize Microsoft 365 integration, enterprise security, and robust video conferencing. Slack is ideal for startups and tech teams that value flexibility, fast integrations, and a modern UI. The best choice depends on your existing tools and workflow needs.
Is Slack a free version of Microsoft Teams?
No, Slack is a separate platform developed by Salesforce, not a free version of Microsoft Teams. Both offer free tiers with limitations, but their ecosystems, features, and integrations are different. MS Teams is tied closely to the Microsoft 365 ecosystem, while Slack is more tool-agnostic.
