Assigning per-user presence policies in Lync Server 2013
Topic Last Modified: 2012-10-11
A presence policy is a set of limits and restrictions that affect presence. The following table describes the presence policy settings available in Lync Server 2013.
Presence Policy Settings
| XML name | Display name | Description | Type | Value |
|---|---|---|---|---|
CategorySubscriptions |
Maximum Number of Subscriber Category Subscriptions |
Limits the number of subscriber category subscriptions. For example, when Communicator subscribes to a user’s presence, it obtains a category subscription for each of the contact card, calendar data, notes, services, and state categories. A setting of 0 means that the user or contact object cannot be subscribed to by others. Note This setting can have a significant impact on performance if it is set to a high number, and the average user has a large number of users subscribing to his or her presence. |
Integer |
0-3000 |
PromptedSubscribers |
Maximum Number of Queued Presence Subscription Alerts |
Limits the number of entries in the prompted subscribers table. This setting determines the maximum number of prompts that can be queued for a given user. For example, when user A subscribes to user B’s presence, user B receives a prompt that user A is now subscribed to user B, and an acknowledgement prompt is created in user B’s prompted subscribers table. After user B accepts, or acknowledges, the subscription, the acknowledgement prompt is removed from user B’s prompted subscribers table. A setting of 0 means that the user is not prompted when someone subscribes to his or her presence. |
Integer or Token |
0-500 |
