Slack Business and Microsoft Teams compete in the team communication and collaboration software category. Microsoft Teams seems to have the upper hand due to its broader suite of features beyond just communication, including document management and video conferencing, which integrate seamlessly with Microsoft Office products.
Features: Slack Business offers strong team communication options with group and one-on-one chats, smooth cross-platform experiences, and extensive third-party integrations. Microsoft Teams provides a comprehensive suite with document management, video conferencing, and deep integration with Microsoft Office, facilitating efficient task scheduling and file sharing directly within its platform.
Room for Improvement: Slack Business could enhance its video call capabilities and improve CRM tool integration. Users also suggest better organization of channels and improved security measures. Microsoft Teams needs improvements in stability, UI enhancements, and performance on lower bandwidths. Users desire better file management features and enhanced integrations with other productivity tools.
Ease of Deployment and Customer Service: Both Slack Business and Microsoft Teams offer deployment across Public, Private, and Hybrid Cloud models. Slack's technical support is highly regarded, with many users finding it reliable, though often unnecessary. Microsoft Teams receives mixed reviews on support, which can vary based on the complexity of user queries and system setups.
Pricing and ROI: Slack and Microsoft Teams offer free versions, but advanced functionalities and large team usage require paid plans. Slack is typically less expensive than Teams, which is part of the Microsoft 365 suite, offering bundled integrations and features. Users find both solutions increase productivity and collaboration, although some consider Microsoft Teams costly when paired with advanced Microsoft services.
Microsoft support is excellent, offering instantaneous assistance through either robo support or live personnel.
We have cases where it took more than six months to resolve very basic issues.
I have logged tickets for Office 365 and received responses within 24 hours, depending on the severity.
We tend to focus more on Workato for support, but internally we raise service requests with the infrastructure team for any issues related to Slack.
When I connected to Slack Business - Enterprise API, tutorials and documentation were available online.
If something was beyond their hands, then it would only be escalated to the external Slack team.
Microsoft Teams is a scalable solution.
Microsoft Teams can be scalable for more than 1,000 people, and I have seen video conferences with 5,000 participants, so the scale is incredible.
I do not see a limit to how many people can be added to Microsoft Teams.
Slack is endlessly scalable.
Slack Business - Enterprise is a scalable product fitting for small businesses as well as enterprises, with no limitations on the number of users.
Slack is not as comprehensive as Microsoft Teams in terms of scheduling and hosting meetings.
I appreciate the ability of Microsoft Teams to control the quality of the call.
Microsoft Teams is stable once the setup is completed properly.
For stability in Microsoft Teams, I would rate it a five.
It integrates with various systems, allowing us to manage site reliability, availability, and reliability.
Slack's stability is a perfect 10.
I do not see glitches, latency issues, or downtime.
AI capabilities should be integrated into Microsoft Teams to provide better transcript services and offer multiple language support.
The biggest issue with Microsoft Teams is switching identities, especially when communicating with external organizations.
Microsoft Teams could be improved through more synchronization with other platforms like Calendly and Gmail.
We can also improve the creation of channels, particularly in terms of privacy, security, flexibility, and the addition of members to newly created channels.
There are a lot of integrations and custom integrations available, but I believe there are opportunities to make those integrations much easier and faster, particularly for business or non-technical people.
I would rate it a ten if it comes with some AI features, particularly using generative AI to produce summarization and other kinds of insights from communication in a more secure, data-secure way.
Microsoft Teams is economical when purchased as part of an Office 365 bundle.
Microsoft Teams comes with Office 365 licenses like E3, but there are options for those who prefer not to pay for Teams by using alternative products like Slack.
Regarding the license, the Microsoft 365 license I am taking is quite expensive, and every year it goes higher.
Teams offers the ability to record sessions and store them in OneDrive, which provides 1 terabyte of space.
The platform is user-friendly and has positively impacted our communication, allowing us to communicate with people from different countries and cities in real time.
The biggest advantage of Microsoft Teams is that it is a combined package where I can do chat, video conferencing, work on spreadsheets, documents, and other things with many people sitting at my desk, which makes work easy, especially with clients who are in remote locations, so it saves a lot of time.
In my experience, Slack is a stable product for communication, and I appreciate its automation features and integration of AI capabilities for enhancing specific functions.
Slack Business - Enterprise is beneficial for us primarily because the API was very beneficial, and that is the main one;
We use the incoming webhook to push end results of automation, which makes our life easier by allowing us to easily check the status of our automation jobs through our corporate phone while in Slack itself.
