Frequently Asked Questions

Slack wins on day-to-day messaging experience: its interface rates 9.2/10 for intuitiveness versus 7.8/10 for Teams, and message search returns results in under 500ms compared with 1,200-1,500ms. It also posts 99.99% uptime and threaded conversations that keep channels readable. Creative and tech teams that live in chat, rather than in Office documents, typically get more value from that speed.
The usual triggers are search latency and interface friction. Teams routes queries through SharePoint and OneDrive infrastructure, producing 1,200-1,500ms message searches against Slack's sub-500ms results, and users rate Slack's interface 9.2/10 versus 7.8/10. Around 62% of knowledge workers express a preference for Slack, and that gap matters most in organizations with light Office 365 dependence.
Cost and integration depth are the main drawbacks. Slack's Pro plan runs $12.50 per user per month against $6 for Microsoft Teams bundled with Microsoft 365, and it ships 100+ native integrations versus 300+ built-in connectors on the Teams side. Free-tier video also caps at 100 participants rather than 300, which limits all-hands use without an upgrade.
Slack remains widely used, particularly in creative and technology organizations that are not standardized on Microsoft 365. Roughly 62% of knowledge workers express a preference for it, driven by sub-500ms message search, a 9.2/10 interface rating and 99.99% uptime. Some companies also run it alongside Teams, using Slack for fast internal chat and Teams for Office-dependent workflows.
Microsoft Teams is dramatically cheaper—at $6/user/month when bundled with Microsoft 365 Enterprise E3/E5, it costs 50% less than Slack's $12.50/month Pro plan. A 500-person company saves $39,000/year choosing Teams. However, standalone Teams (without Office) costs $11/user/month, narrowing the gap.
Slack uses purpose-built full-text search indexes that prioritize message retrieval, delivering <500ms results. Teams prioritizes integration with SharePoint and OneDrive, routing searches through Microsoft's broader infrastructure, causing 1,200-1,500ms latency. Teams is optimized for document discovery, not message speed.
Yes, many hybrid organizations run both—Teams for Office 365-dependent workflows and Slack for faster communication in non-Microsoft departments. However, managing two platforms doubles admin overhead, creates silos, and increases per-user costs to $18.50+/month.
Slack edges ahead for pure-remote teams due to superior UX, threaded conversations that reduce notification chaos, and 99.99% uptime. Teams excels for hybrid workforces that need video calls (300 participants), calendar integration (Outlook), and document co-editing within the same tool.
Teams officially lists 300+ pre-built connectors (Power Automate, Salesforce, Jira, Zendesk), making it stronger for enterprise workflow automation. Slack offers 100+ native integrations but 2,000+ total apps via its marketplace. For custom workflows, Teams' Power Automate and Slack's Workflow Builder have comparable capability.
