Collaboration has transformed how our teams work and Copilot now drives faster daily decisions
The interface for the security and compliance center could be simplified. It changes frequently, which can make it somewhat difficult for admins to stay up-to-date on where specific settings are located. The compliance center modification or improvement of Office 365 needs to be introduced. The rest of the features feel acceptable to me. The reason it is not a ten is because of the complexity of managing the vast array of admin settings, which requires a specialized IT team. Even though it meets industry standards for decent security compliance such as SOC and HIPAA, the complexity of managing the admin settings needs to improve.

Self-hosted file sync tool used to deploy custom web UIs.
I think it’s probably the best self-hosted file sync tool on the market. It’s a full web application platform, an indispensable tool for a business of any size that needs to deploy any kind of custom web UI. If you build an ownCloud app, you’ve got authentication, storage, security, caching, and database layers already fully baked for you. You just need to build your UI and custom logic. Your app doesn’t even need to interact with files, sync, or interact with other ownCloud features. Any web UI can be included without ownCloud. It can even be a portal to web interfaces of other applications within a business using the external app to display external sites within ownCloud. This is the case as long as that site allows itself to be displayed within a frame.

Quotes from Members

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

Pros

"One of the most valuable features of Office 365 is the collaboration capability; multiple employees can work on the same document at the same time, which enhances productivity."
"What I appreciate in the Office 365 world is having Copilot as an assistant that can help automate many things."
"The most valuable feature of this solution is the integration."
"Many of the features in Office 365 are good, but I think Excel is a very good tool."
"Office 365 allows me to access documents and work on them much quicker, and I find it beneficial as it includes Outlook, which improves my workflow efficiency."
"Office 365 is highly reliable; the company hasn't had any issues so far."
"Office 365 has been user-friendly and easy to learn, and collaboration tools such as Teams are very useful, especially when managing our projects and gathering feedback from stakeholders."
"AI with Office 365 is useful for programming, and sometimes for reporting and creating emails, which is easier."
"I think it’s probably the best self-hosted file sync tool on the market."
 

Cons

"Regarding improvement, in Microsoft Word, I suggest addressing the difference in page length between the offline and online versions."
"The stability for Office 365 is not very good, as the application sometimes closes without any information; the old version was much more stable."
"The one big problem with the solution is if you are presenting in Teams and someone puts their hand up, you don't get a notification. If you are running a meeting and just presenting you don't know that people have their hands up and want to ask a question."
"Office 365 tools work very well on Windows, but there is still some lag when using Mac computers."
"The look and feel of the new Outlook is complex."
"Currently, Microsoft can improve Office 365 by enhancing the persistence of the user experience from platform to platform and screen to screen, ensuring that wherever you log in, whatever you're doing, everything is still readily accessible and intuitive, as you left it."
"I think they should reconsider the pricing as it tends to go up annually."
"Office 365 should improve data synchronization, especially when data is accessed through the web interface and SharePoint portal."
"Even with fast disks, it still takes a fair bit of time to write most schema changes to multi-GB tables."
 

Pricing and Cost Advice

"I think that we pay $9.99 USD per user, monthly."
"The pricing is good for all the features that we receive, e.g., Skype for Business."
"Licensing, billing, and accounting are available from the management interface."
"We have a license to use this solution. We have an E3 license which covers many different solutions."
"The pricing is not really high, but one can get the software with the license key for free."
"​The pricing/licensing is easy to manage."
"Most of the time, we purchase Microsoft Exchange licenses, which are less expensive and provide only an email platform and 50 gigabytes of email storage for free."
"The pricing is high and has actually caused us to limit the number of licenses we purchase due to budgeting."
