2. Slack Vs Microsoft Teams- Pricing Plans

Both Slack and Microsoft Teams provide a free version, allowing you to evaluate the app’s quality and some of its features before subscribing to a premium service.

Slack provides an unlimited number of public and private channels and file sharing, 5GB of storage, and 10 app integrations. However, the viewable and searchable message history is limited to 10,000 messages in the free plan.

On the other hand, Teams offers unlimited chat messages and guest access, but file attachments in chat are limited to 2GB, and cloud storage is capped at 10GB for all teams.

Slack Pricing Model

Plan Price (when billed annually) Storage
Pro $6.67 USD/user/month 10GB/user
Business+ $12.50 USD/ user/month 20GB/user

Microsoft 365 Business Basic $6 USD/user/month 1 TB/user
Microsoft 365 Business Standard $12.50 USD/ user/month 1 TB/user

Comparing the pricing plans, Microsoft Teams offers more storage for similar pricing. In addition, Microsoft Teams is already included in the business and enterprise subscriptions. If your company is already subscribed to Microsoft 365, you can use the premium version of Teams without incurring additional costs.

3. Slack Vs Microsoft Teams- Messaging Capabilities

In both Slack and Teams, you can communicate one-to-one or create group chats, which is quite basic. Users can edit, remove, pin, react to messages, and mention another user using the “@” symbol. Users can easily start a new thread, share files, and integrate other applications to help them work more efficiently.

The most significant difference between these platforms is that Microsoft Teams offers advanced formatting options for any text sent in conversations, including the ability to create bullet lists, modify colors, and change fonts.

4. Slack Vs Microsoft Teams- Built In App Integrations

Teams come with deep integration of the Office 365 apps, giving you full access to create, edit, format Word, Excel, PowerPoint, and other Office 365 applications and the ability to interact with team members on a file in real-time.

In contrast, Slack also has Microsoft integrations, such as Outlook calendar and email, OneDrive, and SharePoint, but they aren’t as deep as Teams’ Microsoft 365 integrations.

5. Slack Vs Microsoft Teams Better- Audio and Video Conferencing

Slack offers unlimited one-to-one voice and video calls in its free version. Upgrading to a paid plan allows you to make group audio and video conferencing with 15 members.

But Microsoft Teams allows hosting meetings with up to 100 attendees in its free version, which upgrades to 250+ participants when using a paid plan. Hence, Microsoft Teams is recommended for enterprise customers with large teams.

6. Slack Vs Microsoft Teams- Easy File Sharing and Collaboration

Microsoft Teams allows you to share files and collaborate with your team members simultaneously in real-time. On the other hand, Slack does not have that feature, and you’ll have to download the documents to make changes and re-share them.

With all chats, conversations, shared files, online meetings, tasks assigned, and more available in one app, MS Teams improves collaboration and productivity. Just by downloading the app, your team will be able to access information and connect anywhere, anytime, on any device.

7. Slack Vs Microsoft Teams- Manage Better With Multiple Sub-Channels

Microsoft Teams allows users to create several channels inside a team, making it easier to manage data better and keep track of the growing number of channels. You can also create private channels inside the team to limit access to confidential data. When a Team is created, it automatically gets integrated with the other Office 365 apps.

On the other hand, users in Slack are unable to create sub-channels within channels.

8. Slack Vs Microsoft Teams- Advanced Security and Compliance Capabilities

All of Slack’s and Microsoft Teams’ plans include key security features like two-factor authentication. On the other hand, Microsoft Teams has greater security and compliance options.

You’ll also get full admin controls with Microsoft Teams, including the ability to change member, owner, file, and SharePoint permissions. In addition, DLP and data governance rules can be applied to chat content and files in Teams.

Microsoft offers enterprise-level security features, and Microsoft Teams is an ideal choice for security, as it is governed by Microsoft’s compliance and security rules.
