Office365 This is a new option for acquiring the Microsoft Office Suite. There are 2 Office 365 types of Office 365 subscriptions that contain Microsoft Office user Licenses. One is for the web apps that can open, create, edit Microsoft Office Documents in your web browser. The other is for an actual download and installation of the full version of Microsoft Office on your local PC (and each license allow you to install it on up to 5 of your devices).
Outlook 98 was initially a free download and later remained as a free upgrade for Outlook 97 users adding new features - most notably support for non-Exchange accounts. Its availability has been pulled shortly before the release of Outlook 2000. As its release was outside the normal release cycle of the Office suites (to which the version numbers have been tied), the version number of Outlook 98 could not be a full version higher than Outlook 97.
