While users are adding additional distribution groups to the contact list in Lync, they receive the following message: “Cannot add contact group. The Contacts list already contains the maximum number of distribution groups.” (ten groups)
This happens if you already have 10 groups and you add more groups.
You can change this default setting to a maximum of 64 groups by using the Set-CsClientPolicy powershell commandlet
|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.|
To change the value to the maximum of 64 groups, fire up the lync server management shell and type this command by running the following cmdlet:
Set-CsClientPolicy –MaximumDGsAllowedInContactList 64
If you logoff and logon the policy is applied and your users can add more groups :^)
