While adding additional distribution groups to my contact list in Microsoft Lync 2010, I received the following message: "Cannot add contact group. The Contacts list already contains the maximum number of distribution groups." This article explains the cause of this message and the solution.

 While adding additional distribution groups to my contact list in Lync, I received the following message (Figure 1): "Cannot add contact group. The Contacts list already contains the maximum number of distribution groups."

What Caused This?

I searched through the client management cmdlets in the Lync documentation in the Technical Library and found the following information about CsClientPolicy for the related cmdlets:

MaximumDGsAllowedInContactList

Optional

Integer

Indicates the maximum number of distribution groups that a user can configure as a contact. MaximumDGsAllowedInContactList can be set to any integer value between 0 and 64, inclusive. The default value is 10.

The ability to configure this setting gives administrators more control over this policy than in Communicator. However, the default value for MaximumDGsAllowedInContactList is 10, and this setting may be too low for your users.

Resolution

In my lab I changed this setting to the maximum value, 64, by running the following cmdlet: 

Set-CsClientPolicy -MaxDGsAllowedInContactList 64

Then, I signed out and signed back in and was able to add additional distribution groups.

Summary

At first, this message seems to be an error when, in fact, it is a new setting that you can use for client management. This setting is controlled by the administrator through client in-band provisioning.
