Canceling a Subscription
When you cancel a subscription, the server sends your cancellation notice to the publishing server. The publishing server removes your server from the subscription list for the specified package. If the publisher is not running when you cancel your subscription, the next time the publisher tries to send the package to your server, the publisher is informed of the cancellation and automatically deletes the subscription from its list of subscribers.
Note:
If a subscriber removes a subscription initiated by the publisher, the subscribing server removes the subscription from its subscriptions list, but the subscription is not immediately removed from the publisher's list. Instead, the next time the publishing server tries to send the package to the subscriber, the publisher is notified of the removal and then deletes the subscription from the publisher's list.

2. In the Packages menu of the Navigation panel, click Subscribing.
3. Click Update and Unsubscribe from Remote Package.
4. Locate the package for which you want to cancel the subscription and click the 
icon.
