Office 365 ProPlus is a version of Microsoft Office that’s available through Office 365. It includes Word, Excel, Outlook, PowerPoint, Access, OneNote, Publisher, and Skype for Business as well as online services such as Sway and Power Query.

Office 365 ProPlus is installed on the user’s local computer using a streaming and virtualization technology called Click-to-Run. Office 365 ProPlus is not a web-based version of Office. It runs locally on the user’s computer. Users don’t need to be connected to the Internet all the time to use it.

What is not covered by this certification?

EBS 12.1 and 12.2 are certified with the Office 365 ProPlus versions of Excel, Word, and Outlook.

The following Office 365 ProPlus products are not certified with EBS 12.1 or 12.2:

• Office on iPad and Android devices
• Office Online browser-based versions of Excel and Word
• PowerPoint, Access, OneNote, Publisher, and Skype for Business
• Online services such as Sway and Power Query

Click-to-Run delivers monthly updates to Office 365 ProPlus

By default, Click-to-Run products are configured to be updated automatically every month. Users don’t have to download or install updates. The Click-to-Run product seamlessly updates itself in the background.

Microsoft also offers a semi-annual channel for updates in January and July, as well as a targeted semi-annual channel in March and September.

Certification with Click-to-Run updates

Oracle certified EBS 12.1 and 12.2 in September 2017 with the latest available versions of Excel, Word, and Outlook in Office 365 ProPlus at the time.

Microsoft’s updates to Office 365 ProPlus are intended to be backwards-compatible. This means that Oracle’s certification with the September 2017 baseline should continue to apply to Microsoft updates in October 2017, November 2017, and so on.

It is unlikely that Oracle will be able to certify all monthly Office 365 ProPlus updates with all EBS 12.1 and 12.2 updates. Given Microsoft’s stance towards backwards-compatibility, this is theoretically unnecessary.

It is expected that Oracle will continue to certify selected updates to Office 365 ProPlus versions of Excel, Word, and Outlook with updates to EBS 12.1 and 12.2.
