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

"Office 365 has excellent facilities, it's familiar, and it's easy to comprehend when sending messages."
"Office 365 has AI capabilities that improve our processes, as we are using Copilot to assist us in writing documents."
"I find OneDrive valuable because I'm able to have all my documents in one place and I can access them from anywhere."
"It's easy to expand and add new things like Google Docs and new PowerPoints."
"It has all the business tools that most companies require to run a business effectively."
"Office 365 has significantly enhanced collaboration and productivity through integrated tools like Teams, Excel, and Power BI."
"The features I find most valuable in Office 365 include its user-friendly interface; we use Outlook, Teams, and SharePoint for various tasks, and overall, it is helpful."
"It has everything one would need to run a modern office, providing every solution we require."
"I think it’s probably the best self-hosted file sync tool on the market."
 

Cons

"Be sure you understand ADFS and, if you decide to go with it, what you get and don't get with it."
"The feature to convert PDF file to a Word document needs improvement as well as the feature to save the file automatically when typing, without using the save command."
"Office 365 is not cheap for individual users."
"I found the initial setup of Office 365 a bit cumbersome, so I used a technician."
"Office 365 experiences several performance issues, particularly in Excel and Word, including lagging and delays."
"When sharing documents, having a feature similar to a Box note would allow quick jotting down of ideas without the need for structured and aesthetically pleasing formats, making it easier to share thoughts promptly."
"The stability for Office 365 is around a seven or eight; it could be more stable, especially when doing co-authoring; applications may freeze or changes may not get reflected quickly enough on the remote end."
"I rate the support of Office 365 a four out of five."
"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

"Good reporting and good value subscriptions for international calls."
"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."
"Licensing fees are paid on a monthly basis, or we prepay them."
"​The pricing/licensing is easy to manage."
"For the moment, we are paying on a monthly basis because we are still adapting the support and how we want to proceed. I think we will move to paying for the annual license."
"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."
"I would rate the solution 3 out of 5 for the price. I think Microsoft presents a good solution concerning the price."
