"Cannot add contact group. The Contacts list already contains the maximum number of distribution groups" when a Skype for Business Online user adds a contact group in Lync
When you try to add more distribution groups to your Skype for Business Online (formerly Lync Online) contact list in Lync 2010 or Lync 2013, you receive the following error message:
Cannot add contact group. The Contacts list already contains the maximum number of distribution groups.
You can't increase the limit in Skype for Business Online. However, users should review the following Office help topics about how to manage contact lists for best practices and guidelines:
This issue occurs because the maximum number of distribution groups that a Skype for Business Online user can have in their contact list is set to 10 and can't be changed.
This restriction applies only to distribution groups from the address book. It doesn't apply to contact groups that are created by the user.
