Frequently Asked Questions: Teams vs Slack

QIs Microsoft Teams better than Slack?
It depends on your existing software stack. If your business uses Microsoft 365 (Outlook, SharePoint, OneDrive), Teams is the clear winner — it is deeply integrated and included in your subscription at no extra cost. If you use Google Workspace or need best-in-class third-party integrations, Slack may be better. Teams wins on video meetings and file collaboration; Slack wins on messaging UX and app ecosystem.
QHow much does Microsoft Teams cost vs Slack?
Microsoft Teams is included free with all Microsoft 365 Business plans ($6–$22/user/month). Teams Essentials standalone is $4/user/month. Slack Free is limited to 90 days of message history. Slack Pro is $7.25/user/month, Slack Business+ is $12.50/user/month. For Microsoft 365 users, Teams is effectively free — making it the obvious choice from a cost perspective.
QCan I migrate from Slack to Microsoft Teams?
Yes. Microsoft provides a Slack migration tool in the Teams Admin Center that imports channels, messages, files, and members. The migration preserves message history, reactions, and file attachments. Our team handles Slack to Teams migrations as part of broader Microsoft 365 tenant migrations, ensuring all historical data is preserved.
QDoes Microsoft Teams have better video calling than Slack?
Yes, significantly. Teams supports up to 1,000 participants in meetings, has built-in webinar hosting (up to 10,000 attendees on Business Standard), and includes advanced features like breakout rooms, live captions, meeting recordings, and Together Mode. Slack video calls are limited to 50 participants and lack many of the enterprise meeting features Teams offers.
QWhich is better for remote teams: Teams or Slack?
Both work well for remote teams, but Teams has an edge for Microsoft 365 users because of its integration with Outlook calendar, SharePoint files, and OneDrive. Slack has a better messaging experience and more third-party integrations. For teams that primarily communicate via chat and use many different SaaS tools, Slack may feel more natural. For teams that rely heavily on Office documents and video meetings, Teams is superior.
