As a cost saving measure, most customers choose to let each user install the new Office desktop client on their PC. However, we can optionally provide this service for you. If you have issues getting the upgrade to work, we’ll support you with that.
Organizations with a large number of users can benefit from having us package the Office 365 installer and deploy it to a shared folder on the local network. If you have more than 50 users in your organization, you should ask us about this option.
