The Bond University Office 365 accounts don't have access to the Office store. However, if you sign out of your account and then add the RefWorks Office Add-in, you can then sign back in and the add-in is still fully functional.
Whilst signed in with an Office 365 account, you may see the following:
Click on the House icon at the top of the Microsoft Word window
Sign out of your Office 365 account
Go back to 'Insert' and then 'Get Add-ins'
Enter 'Refworks' into the search field and then 'Add'
And then Continue
You can then sign back into Office 365 by clicking on the Home button
If for some reason the RCM tab is not present whilst signed into Office 365, you may need to click on the 'My Add-ins' and then start the plug-in up again.
