Office 365

Avantages

Tight integration with Microsoft Outlook (unlike other email platforms). This is most noticeable with contacts and calendars, including sharing. The subscription-based model allows for easy updates to the latest Office software while being able to control if those updates should be deployed at all. This helps to keep all users on the same version without the concern of having to buy upgrade licenses and perform a traditional software rollout. The ability to save directly to OneDrive and/or Sharepoint with applications such as Word or Excel is extremely valuable and is a great solution for small organizations that have no local central storage or tend to save items directly on their own PCs. Email accessability is simple via web, mobile, and desktop. Storage space is sufficient and can be expanded easily (for an additional cost). Tenant management is very easy to use and navigate - most areas are very self-explanatory (help is easily accessible as well).

Inconvénients

Office 365 has matured quite well. Early on, tenant management was a little clunky and over time features have been added. A wish-list item would be wider acceptance for OneDrive integration with 3rd party apps - similar to DropBox.

Avantages

Teams is a very user-friendly application that facilitates communication between individual users and whole departments. IM capabilities mean that users can message one another to collaborate on projects and share ideas. Files and documents can be shared with others, and Teams also has audio/calling conferencing capabilities (part of Microsoft's vision to deprecate Skype for Business in favour of Teams) meaning users can meet and share ideas even if they are at home or away from the office. The mobile app allows you to chat to colleagues when you aren't at your desk. If users are part of a departmental team, they can view these teams within the app; they can message other team members, share files, and use other Microsoft-specific apps such as Planner or SharePoint if they have been set up. Meeting scheduling is also available from within Teams, linking up with your Outlook calendar. For administrators, it is easy to deploy and maintain the Teams application using GPOs, and the application itself is self-updating on startup.

Inconvénients

Teams currently installs to the user's 'AppData Roaming' folder, which means that it is installed separately for every user that logs into the computer. It is quite resource intensive to run the applications compared to other communications apps. However, both of these issues have been flagged for review on the Microsoft Teams suggestions and feedback website, suggesting they will be rectified in a future release.

Avantages

I love that Microsoft has invested so much on Office365 (obviously since it's a major bread-and-butter source of income for them). Given this, you really feel that MS has a great and huge team behind it. And so, I love that it keeps on improving over time via the regular updates and patches. Now, I feel that I get the new features soon after it gets released, and I feel secure as well from threats of malware, bad scripts, macros, and what have you.

Office365 is the office we have grown up with in the boom of word and spreadsheet processing. This is a must for compatibility issues as most, if not all, of my contacts use MS products. And so, to avoid incompatibilities, or having to destroy the document layout and formatting, better use the same Office365 (and oh, btw, it is also backward compatible for those left behind in the MSO standalone versions).

Office365 is also connected to my MS OneDrive, and so all my documents are readily accessible in one place. Also, this allows me to share my documents to other people and to work on them together. Pretty cool.

Inconvénients

Compatibility with other word/spreadsheet processor apps out there like LibreOffice and GoogleDocs/Sheets. Why can't they just agree on how to save and handle documents, eh? The closed source nature of MSO365 makes it difficult at time to work with other apps mentioned as it destroys the formatting most of the time. So, I tend to share via PDF, but that is not editable.

Avantages

Office 365 was a powerful move to the cloud and leveraged the familiarity of the Office Suite with the connectivity and enabling of collaboration on the cloud. At first, the cloud versions of familiar software was rough around the edges and missing a lot of the functionality that people knew in the desktop versions, even if they didn't use them regularly (or ever). Over time, Office 365 has steadily improved its various offerings, added more feature parity between the desktop and online versions and begun to integrate more seamlessly with workflows for a variety of people. With some vision of what "work" looks like outside of generating letter-size pieces of paper with text and images on it, the variety of tools surrounding the classic presentation, word processing, and spreadsheet software have introduced new methods for communicating and creating content together.

Inconvénients

Sometimes the level of options can be overwhelming. Even with a fair amount of experience, it can be tricky to stay on top of changes or know all the ins and outs. The rapidity with which they address fixing problems is also applied often to perceived problems and that can lead to feeling like the documentation is always out of date or non-applicable and no one knows the right or simple answer to things.

Avantages

As a Microsoft Office user for 12+ years, Microsoft has done a lot to innovate their productivity platform. In particular, Office 365 has tons of differentiated value:
1. You receive unlimited upgrade rights to the latest versions. No other types of productivity software provides this option.
2. The amount you receive in the suite is amazing... from Outlook to OneNote to Publisher, the Office Suite gives you the tools you need to transform your business.
3. Co-authoring - This is not just Office to help you be productive. This is Office that allows everyone to be productive at the same time. The co-authoring feature allows people to collaborate and work on documents together even if they're on the opposite sides of the world.
4. Office 365 is secure. The concept of no news is good news applies in this case from a security perspective. Microsoft does an excellent job ensuring that their user's data is secure in the cloud, and that alone is one of the most important differentiated value.
5. The UI is easy to navigate through, and I have personally taught both kids and older folks how to use Office 365 in minutes. Microsoft did a great job creating a navigation pane that is easy to go through.
6. Office Mobile is also great. As a mobile user that travels a lot, it's very helpful for me to view documents through my phone and still be able to view and edit the rich features of Office. I can't say this applies to Microsoft's competitors.

Inconvénients

There are a few cons as it relates to Office 365:
1. For those that are finance conscious, the subscription model does not really resonate with everyone. And if you want to buy the perpetual license, it's ridiculously expensive...
2. Skype for Business needs to stop dropping users from calls in the middle of calls. It happens too often, and even though the potential solution is to move to Teams, Skype for Business in terms of quality calls, needs to stand alone and work better.
