Why choose Microsoft 365 over Microsoft Office?

If you decide to access Office apps on multiple devices, collaborate with other users in real time, have constant access to updates, and enhanced security, Microsoft 365 may be a more affordable choice than purchasing Microsoft Office individually. Specifically, Microsoft 365 works via subscription for access to all Office apps and other services such as OneDrive, SharePoint, Teams and more. 

The advantage is definitely accessibility: installing Microsoft 365 offers access to Office apps on all devices, including smartphones, tablets, PCs, and Macs. In addition, you can access your files and data anywhere there is an Internet connection. With Microsoft Office, you must instead purchase and install the apps on each device separately.

Microsoft 365 is constantly being updated with new features and bug fixes, plus it offers many collaboration options, including tools such as SharePoint and Teams, which allow you to work together in real time on documents and projects. These are features that are not reflected on all available versions of Microsoft Office, so it is an important element to consider.

And if you decide to buy and download Microsoft 365 on Mr Key Shop, in addition to all these advantages, you also get a highly professional, prompt and transparent service. All this is proven by our average score of Excellent (4.9 | 5 out of 5 stars) on TrustPilot, where more than 2,000 positive reviews confirm the quality of our service, which has been available for more than 18 years in the digital market.
