Assume that you start an instant message conversation or a group conversation in the Skype for Business 2015 or Skype for Business 2016 desktop client. When you select the Invite More People button in the open window, and you search for a distribution group (DG), no result is displayed and you can't invite the DG members to join the existing conversation.
This is a known issue. To work around it, use one of the following methods:
- Method 1
In the Skype for Business main window, search the distribution groups (DGs) in the Find someone area, and then drag the desired groups to the existing conversation.
- Method 2
Start an Audio/Video call or a conference instead of an IM conversation or a group conversation. Then, you can search the DGs in the opened window and invite the DG members to join in the conversation.
Note Please be aware that the Audio/Video call or conference requires additional network bandwidth. This might affect network performance during times of heavy traffic.
