The Office 365 service relates to subscription plans that offer access to the latest and most actual versions of applications of the Office family. Office 365 includes Skype for Business, Exchange Online and OneDrive for business as well. Individual Office 365 subscription plans let you install full versions of application such as Word, Excel, PowerPoint, OneNote and Outlook on multiple devices – PC or Mac computers and mobile devices. Office 365 users can take advantage of technical support without additional costs. You can also buy Office as a standalone product; in this case, however, if new application functions are introduced, your software will not be updated with them.
