Executive SummaryUpdated on Nov 9, 2025

Yammer and Slack Business - Enterprise compete in the collaboration platform market, each enhancing organizational communication. Slack tends to have the upper hand due to its superior features and robust integrations.

Features: Yammer focuses on enterprise social networking through community building, content curation, and threaded chats. Slack offers extensive integrations, customizable notifications, and real-time messaging, improving team collaboration with its channel organization and search functionality. Slack's diverse app ecosystem provides flexibility for dynamic work environments.

Room for Improvement: Yammer could benefit from deeper integration capabilities and faster customer support response times. Its feature set might also need enhancement to compete with more integration-heavy platforms. Slack, on the other hand, could improve on pricing to make it more accessible, enhance its user interface for greater intuitive use, and address concerns about information overload within channels to streamline user experience.

Ease of Deployment and Customer Service: Slack Business - Enterprise is praised for simple deployment and a robust API for integration. Its customer support is noted for quick, detailed responses. Yammer integrates easily within Microsoft environments but lacks Slack's integration depth, and its support, while reliable, doesn't match Slack's speed.

Pricing and ROI: Yammer is more cost-effective, often included in Office 365 plans, making it attractive for Microsoft-centric organizations. Slack requires a higher investment but provides strong ROI by enhancing team productivity through its integration capabilities. While initial costs for Slack are higher, its comprehensive features justify the expense for teams seeking versatile collaboration.

Akhil Viswam

Senior Consultant at a consultancy with 10,001+ employees

Threaded collaboration has transformed how our team tracks tickets and monitors automation updates

One suggestion I would make for improving Slack Business - Enterprise is the support of multimedia such as images and videos that we can easily share through Slack. That would be great. Additionally, another thing is AI integration; if Slack has some AI capabilities to get insights about conversations or summarization, that would be a great feature. If Slack has an AI feature that can summarize a particular Slack thread and provide a summary of that, that would be a great feature for us. 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.

Deep Bhowmik

Senior Technical Product Manager at a manufacturing company with 10,001+ employees

Creates user groups and streamlines communication

I think we should have some improvements in Yammer, similar to what we have in Facebook and others, where we can have targeted communications, so that we can filter some communications to go to a specific subset of that group, not to everybody. We would love to have some AI technologies included in Yammer, but I do not have a specific use case in mind right now.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"One thing I like about Slack is the ability to change the color of Slack. It depends on my mood. When I'm having a bright day, I just change the background color of my Slack, which is nice."

"Slack Business - Enterprise has had a positive impact on our organization with better communication, provides faster response times, fewer emails, and has helped create a more agile company."

"In terms of setup, approaching its menu is simple."

"Slack Business - Enterprise has impacted our organization positively; it is performing very positively compared to other chat applications and is very helpful at an enterprise level to keep track of everything in separate threads."

"We use thread-based communication. So that if a new person comes to look into a problem for a particular task, they can easily go and look into the particular thread it is discussed in."

"Slack's stability is exceptional."

"The huddle feature that allows you to get on a call with a colleague is one of the best features of Slack."

"The solution makes it easy to create groups, share documents, and communicate."

More Slack Business - Enterprise pros

"It's really easy to use the solution."

"The most valuable feature of Yammer is its integration with all the services of Office 365."

"The most valuable feature of Yammer is that it provides integration with Teams."

"The design of the solution is its most valuable feature."

"The tool allows us to post and keep track of company buzz and events without relying on email."

"The product's initial setup phase was straightforward."

"Yammer shows the post’s actions, comments, and how people react. We can quickly see what's going on."

"The initial setup was simple and straightforward."

More Yammer pros

Cons

"I would like to be able to do live streaming on Slack. Slack allows Slack huddle where you can do a group call, but it is not very well-designed. I'm not sure if it is going very well, but live streaming is one thing that I would definitely love to see. When you use Zoom, I like how you can run webinars. If we could do that through Slack, it would become an all-integrated platform. I would also like to be able to schedule meetings using Slack, similar to Zoom."

"The reason is we are moving towards a new CRM, so we have a suitable solution to integrate with the new CRM."

"I have found it cumbersome to create and set up groups, or channels."

"The UI could be a little bit better."

"We do experience issues when trying to log in on Slack."

"Sometimes, the servers are not available."

"From my perspective, a disadvantage of Slack compared to Teams is that connecting between the apps can be a bit difficult."

"Slack's channel and chat management could be more intuitive."

More Slack Business - Enterprise cons

"Yammer's UX and UI are areas with certain shortcomings where improvements are required"

"It should have integration with multiple third-party platforms."

"Yammer has very limited features."

"Yammer should offer flexibility to allow branding without writing any code."

"Yammer should be able to integrate with Microsoft products, such as Outlook."

"I faced some issues with Yammer's mobile app when I shifted from Android to iPhone, and it got a little bit tricky to use it on an iPhone, which took away some of my time."

"The way you want to control the communication could be an issue. It depends on what kind of company you are. We are a public company, and there are some regulations that we need to comply with. Its ease of use can be an issue for a company because anybody can subscribe and use it. There are many competitors that are overlapping. Since Microsoft bought Yammer, it tends to be in the shadow. It is not put in the front from the service perspective."

"It has a very limited use."

More Yammer cons

Pricing and Cost Advice

"It is an affordable solution."

"It is less expensive than one of its competitors."

"When it comes to pricing, it is on the expensive side."

"The solution is expensive."

"We use the free version that does not have a license."

"The pricing can range up to about twenty bucks a user. You can spend a lot of money, especially if you're talking about thousands of users. Generally speaking, Slack is less expensive than Teams. Slack doesn't include all the bells and whistles that Teams does. So you can go from a $6 license in Microsoft 365 to a $50 license per user per month, and there's a lot more you can do in the $50 license."

"The solution’s pricing is cheap."

"The tool's pricing could be cheaper."

More Slack Business - Enterprise pricing and cost advice

"The pricing is not bad."

"I think that there is a need to make yearly payments towards the licensing costs of the solution."

"Compared to other products like Amazon, Yammer's pricing is fine."

"I don't know about the pricing. Now that Microsoft has bought Yammer, it should be a part of our subscriptions for Office 365."

"We get it as part of our Office 365 subscriptions, so I don't think we pay any additional cost for Yammer. It's included in the Office 365 subscriptions."

"Yammer is a pretty cheap solution, and it's included in multiple subscriptions."

"Its cost is included in the license bundle for Microsoft."
