The wider adoption of Slack by users is hard to compete with. Slack is integrated into far more services and apps than Teams and that makes it a better service. Teams would be a better product if its API was used by more third-party services and Microsoft did not force users …

There really are few viable alternatives to Microsoft 365 Business Premium. Organizations can either use Google, Microsoft 365, or an amalgamation of Slack, Zoom, and Google/\Microsoft. For organizations that already use Microsoft, it's convenient to upgrade rather than …

Against the most common competitor/peer of the Apple Pages/Numbers/Keynote suite, Microsoft 365 absolutely demolishes. It's hardly a fair fight considering the ease of use Microsoft products enjoy on Apple hardware despite the companies being direct competitors. Apple knows …

It was not my decision to move to Office 365 for Business. We have used Google for Business in the past, as well. Both are good and it's mainly more of user-preference that sets them apart.

I think Slack works really well in office settings, or even for any group of people who need an easy way to communicate with each other through organized channels. It may not be the best for those who intend to use it as a social media type app, it is more geared towards business use.

Pros
Microsoft
  • Work in sync in different departments.
  • Being able to work from any device or computer. It is a very noble tool in different devices.
  • The work between the different programs (Word, Excel, Notes) that it offers is extremely light and good.

  • Automated Notifications: Integrated tools like Jira, Trello, and Google Drive to receive automated notifications and updates directly in Slack, improving visibility and efficiency within the team
  • Message Encryption: Slack encrypts the messages in transit and at rest, ensuring the security and privacy of sensitive information and making our IT team's life much easier.
  • Reminder Bots: We used Slackbot to set reminders, automate follow-up actions, and provided information based on user queries.
  • SurveyMonkey Integration: Integrated our Slack with SurveyMonkey to distribute surveys and collect feedback from team members, streamlining the feedback-gathering process which was a huge support to our HR and Admin team.

Cons
Microsoft
  • The only thing that is a bit cumbersome is that it doesn't seem that you can save files directly to programs like one drive if you aren't using a Microsoft program to generate the document. An example of this would be if I am working in a PDF in our PDF Program I have to first save it to my desktop and then drag it into one drive. I end up with duplicates and that can sometimes make it hard to remember which is the most up-to-date.

  • The only thing I can think of is that it is easy to create too many channels. This has more to do with the team using Slack and less to do with Slack itself. maybe some direction on Slack's part on how best to utilize channels would be helpful.

As useful as Slack has become within our company, I feel fairly confident we will continue to use Slack as a communication tool. They continue to improve their software and add value to its use within our office. Customer service delivers, which is an absolute must. Looking forward to how they improve.

Usability

The basic apps are straightforward and easy to use, especially since they have been around so long. I'm referring to the basic apps like Outlook, Excel, Word, PowerPoint, OneNote, etc. Other features such as Microsoft Teams and Sharepoint Sites, Sharepoint Lists, Sharepoint Groups, etc. all require a higher level of knowledge to both implement and use properly

As long as you use the basic chat features and nothing more, it really is super easy to understand and use. Once you want to take advantage of some of the more advanced features and capabilities, that's when things get complicated. Anyone who has use SMS or a chat program before will be able to figure out the basics though, so rolling this out should be relatively straightforward and not required exhaustive training. Teaching chat etiquette is something else though.

Performance
Microsoft
In the last 5 years, Microsoft has come a long way. The performance of the products has become more and more user-friendly and it seems that the feedback provided by the user community is being listened to and worked on. The processes are very fast and seamless. There are negligible errors and doesn't slow the systems down.

As mentioned elsewhere in the review, Microsoft has historically paid attention to community feedback and issues, but timeliness can improve, and so can the addressing of long-standing issues about which many users have said "I have this issue too!" but no official solution exists. For issues that do have a solution, however, the solution is usually not difficult to find, and the explanation of features on Microsoft's website can mitigate many problems.

I've never had to contact support for Slack which is a great testament to its ease and use. Adding people outside of the organization takes a little getting used to, but ultimately allows for greater collaboration between FTE and contractors. There is no clear alternative to this software, so it's the best we can do for now.

It always helps if you communicate to everyone in the organization how important it is to drop whatever other chat tools they are using and jump quickly to Slack. They will all fall in love with it.

Alternatives Considered

Before migrating to Microsoft 365 Business Premium, we possessed an in-house exchange server. Therefore, it was difficult for us to look at alternatives to Microsoft for a solution – we did look at the Google Suite of products, but the transition for us seemed less cumbersome to stay with Microsoft from a staff and administrative perspective. While the G Suite does offer us many outstanding products and services, we also didn’t feel that Gmail is up-to-par as a corporate solution the way Exchange/Outlook/OWA are – this alone was also a driving force for our end-users, as there was minimal transition for them to move from an on-premise solution to an off-premise solution. The additional features of SharePoint, Teams, Project, and so many other applications within Microsoft 365 also helped us make a strong case to stay with Microsoft and expand what we were using. The end-user and mobile protections of InTune have also put us at ease when issuing laptops and mobile phones to an almost fully-remote end-user base.

Slack is the superior offering for what we do and who we communicate with. The other programs offer basic features, but Slack continues to innovate and is business-first, which is very helpful for our small team. The feature set and integrations are better in Slack than other offerings we have evaluated

  • Teams has streamlined our chats within each department so its easy to help out each other when problems or issues arise as well as having chat conversations in real time instead of the slower email option. This is especially handy when peopel are not working in the same space and cannot use a phone.
  • All of our major communications, are done through Outlook email keeping everyone on the same page of issues within our organization or updates coming out for example
  • Excel provides a simple system for creating our schedules, Tracking customer issues, project boards etc. having all these readily available minimizes time spent looking for information and grants more time for customer interaction and increasing service and sales.

  • We have a story when one guy mentioned in a our site group with tag @here about his wedding, he didnt know that @here works only for people who are online, so most of the people missed the message, slack is not the best place to update about the important things
