The Office online integration has been developed to provide a comprehensive, native and seamless experience, allowing you to add, view and collaboratively edit Microsoft Office documents online.
You need a valid Microsoft Office Online account to enable and use this feature, and HighQ must activate Office Online support at the instance level; please contact HighQ support.
Enabling office online at system level
Once HighQ support has activated this feature at the instance level, it must be enabled at system level by a system administrator. As a system administrator, navigate to your drop-down menu > System admin. The system admin screen is displayed. Within the System admin screen, navigate to System settings > Open in office online:

And ensure that the drop-down is set to On.
Click Save to save your changes. Office Online is now enabled at the system level.
Enabling office online on a site
To enable Open in Office Online on a site, either you or a site admin must navigate to site Admin > Files and select the Enable Open in Office Online checkbox:

Click Save to save your changes. Open in Office Online is now enabled for your site.
Enabling Office add-ins
There are a range of add-ins available for Microsoft Office Online. You may install add-ins to benefit from additional tools when working on a HighQ document.
For security, a system admin must first configure a list containing the IDs of all plug-ins permitted on the instance.
System admin settings
The ID for each add-in that will be installed must be added to system settings by a system admin.
Open System admin from your profile menu, then select System settings in the left-hand panel.
Scroll down to Office Add-ins id:

This field must include a comma-separated list containing the IDs of all plug-ins permitted on the instance.
Finding the IDs
Click the Microsoft AppSource link to open the library of add-ins.

Click the add-in and check the URL in the browser's address bar (highlighted below):

Copy this ID and return to the System settings page.
Scroll down to Office Add-ins id:

Add the ID to the comma-separated list and click Save.
Users may now add the add-in to Office Online.
Adding the add-in to Office Online
Open a document in an Office app, such as Word Online.

Add-ins are displayed in the toolbar. To configure an add-in, select the add-in icon in the right-hand toolbar.

At the bottom of the add-in panel, click Allow and Continue to add the add-in to the toolbar.

Using an add-in for the first time
Click on the add-in icon in the toolbar.
Due to security settings, Office Online displays an error message:

Close the document (i.e. close the tab containing the document), then re-open the document from the files list.
The add-on now works as expected for any document opened with this Office Online app.
