I have been working with various projects in our mail surroundings and also on security tools.
I assess that Office 365 has a lot of integration work done in applications such as Word, Excel, and Outlook with OneDrive for cloud storage, and that is a really good thing for us.
When we have projects, we make a team in Teams, and this allows us to make meetings faster and organize them more effectively. We can share data in these meetings much faster and more easily than in the past.
I assess the effectiveness of Office 365's advanced security measures, such as multi-factor authentication and data loss prevention, positively. We are using multi-factor authentication and have strict rules that allow it to be used only with hardware in our Active Directory, for example. We are using Intune to make the hardware more secure.
I know we have the licensing for Office 365. I know we have license E3, for example, and Premium Basic. As a customer, I would say it could be cheaper, but it is acceptable from the structure, and I can understand it.
I think it is worth the money that we pay for it.
We do not use any official documentation offered by Microsoft. We make our own documentation because of laws, justice, and requirements here in Germany, and we use our own tools for this.
Based on every aspect of Office 365 that I have worked with, I would rate it an eight out of ten.
