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 …

Microsoft 365 Business Premium is well suited to any size organization and is a must-have for business purposes. It is a vital component for the majority of work software needs, as the Microsoft 365 Business Premium package has apps to handle needs that I didn't know we had. It is a great way to provide the required software programs to teams, especially those that work remotely due to the great sharing capabilities built into it. Furthermore, the nonprofit program provided our small nonprofit with vital components for our remote work, while allowing us to keep our donated funds going directly to our mission.

If you population likes technology, then I would recommend Slack. It is more difficult to implement if not everyone is on Slack or knows how to use it. Slack was used well by some employees who loved it. Slack allowed them to plan annual events and get feedback and ideas from those involved in the event

Cons
Microsoft
  • adding calendar invitations is not straight forward
  • copying folders from SharePoint libraries to an external drive should not be relying on the available space on the C drive
  • administering mailboxes for our company is convoluted forcing me to hunt for settings and options
  • lack of flexibility on the location of the OST and PST files
  • the new version should not do away with PST files but rather improve their reliability.
  • the PST internal structure is inefficient. the PST file should be able to shrink automatically when one delete emails.

  • Would love a better integration with GitHub. For example, notifications when your PR is updated, when review is requested, @-mention in comments, etc.
  • Improved "Later" tab, for example the ability to create to-do lists or making the "Later" tab into a more powerful to-do list (annotate items with notes)
  • More powerful integrations, e.g. Google Calendar could render a calendar view within Slack, rather than sending the daily schedule

To be more transparent, I give 10 because Slack serves our collaboration needs. It provide us a good platform for team communication relaying important update within the company, it has even mobile app where you can install in your phone to monitor any updates within that team that needs your immediate attention and intervention.

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

Slack is one of the easiest platforms to use! It is very aesthetically pleasing and you can arrange the chats and other features the way you personally like it. They kept it pretty simple for people who aren’t looking to do anything more than streamlining communication, but they definitely have options for folks to build out the Workspace more.

Yes, the app works 24/7. I don't even recall having any period that we could not use since the implementation. Even the maintenance periods are barely noticeable and our work is not impacted by it when it happens.

Performance

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.

Slack is a soft app, we don't have many issues with it. I recall one or two people complaining about something during our usage period, but I didn't have a bad experience. When the app is slow, usually the problem is with my computer or my internet. The app works just fine.

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.

Whenever I've had to troubleshoot an issue with Slack (which, to be honest, has not happened very often), their online documentation has been easy to locate, easy to understand, and effective in resolving my issue. Slack's ever-growing popularity also means that there's a large community of practice out there that can be depended upon.

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.

Having had a lot of experience with Google Chat and Teams, Slack is far and away the better option. In comparison to Teams, Slack is much cleaner with a far more user friendly AI, Teams is far too clunky and feels tiresome to use, whereas it is super easy to pick up Slack and be able to configure it do exactly what you need. Whilst I don't find a massive difference between the usability and UI of Google Chat to Slack. Slack's range of features far outweighs Google Chat. The ease of external connections, workflows, file sharing, external connections for notifications (Make, Zapier etc), plus the huge range of apps you can connect to enhance your workspace is incredible. Google Chat does benefit from directly integrating into your Google Suite so you can get access to automatic status updates based on calendar activity, which would be nice for Slack to have
