Find out if you have access to Connections
To use Connections, you must have a subscription to Office 365 Business Premium.
You can easily see if you have access to Connections, and other Business apps in the Office 365 admin center:
Sing in to your Office 365 account with your admin credentials.
In the admin center, expand the left nav, and go to Settings > Services & add-ins.
If you have access to Connections, you will see Business apps listed on the Services & add-ins page.
Connections is only available to Business Premium accounts. You can check the Microsoft Business center card on your admin home page to see if you have access to Connections. If you are on Business Premium but don't see Connections, it is because Connections is still being rolled out to all Business Premium organizations and it might take some time before it is made available to your orgnanization.
If you do not have a subscription to Office 365 Business Premium and want to change your subscription, see Switch to a different Office 365 for business plan.
