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

"The most valuable features of Slack are basic chatting, file sharing, and screen sharing."

"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."

"Slack makes it easy for employees to contact each other and exchange documents or information."

"Slack is a very collaborative tool that makes it easier for me to communicate with the onboarding and billing teams."

"When we work with a platform like Slack, we can have one source without merging different document versions."

"The most valuable feature is the screen sharing, which works well."

"Its integration with different apps is a great feature."

"It allows to facilitate communication, allowing us to create channels for updates, file sharing, and photo sharing within our team profiles."

More Slack Business - Enterprise pros

"The user interface and the way we can share and search information are the most valuable. It is very easy to use."

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

"People share their files and ideas and attend meetings in a collaborative manner."

"Groups is the most valuable feature in Yammer."

"The initial setup was simple and straightforward."

"Its most valuable features are the storyline and communities."

"I find it quite simple and intuitive. It's similar to using a more user-friendly interface for SharePoint. It integrates seamlessly with the browser, so you hardly notice you're using it."

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

More Yammer pros

Cons

"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."

"Sometimes, the servers are not available."

"I would like the text in chat to be more customizable."

"It could be more stable than one of its competitors."

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

"When showing screens during calls, the screen sharing functionality is not as smooth as Google's offering. It appears to be designed for short calls, which limits its effectiveness for longer sessions."

"For me, the only thing I can say is that every time somebody sent me an attachment, the attachment was listed somewhere, and then I had to open the conversation and go to the individual to open it. So there is no handy repository or an easy way to quickly look at attachments. For me, that was a bit difficult."

"Slack's interface is not simple for me. It's not a user-friendly interface"

More Slack Business - Enterprise cons

"I would like to see a fancier user interface. That is one of the weak points of Yammer."

"It has a very limited use."

"This solution would be improved if it was well integrated with other communication applications."

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

"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."

"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 permissions are a little bit over-complicated."

"I would rate the stability of Yammer as six out of ten."

More Yammer cons

Pricing and Cost Advice

"Slack is definitely worth the money."

"The solution is expensive."

"I would rate the tool's pricing a four out of ten."

"It is an affordable solution."

"The solution is cheap in my country."

"The solution’s pricing is cheap."

"It is an expensive tool. We pay 15 to 20 USD monthly per user."

"The tool's pricing could be cheaper."

More Slack Business - Enterprise pricing and cost advice

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

"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."

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

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

"The pricing is not bad."

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

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