How to start Private Conversation – Skype
1. Click on the + ICOn next to New Private Conversation.
2. Select the contact your list and invite to accept your invitation for Private Conversation.
3. Once the invitation accepted you can start the private conversation with the specific device. Note the invitation is valid only for 7 days.
Now you can test Private conversation by downloading insider version 184.108.40.206, but bear in mind the other person also needs to use skype insider to start the Private conversation.
During the preview, you will only be able to start private conversations with other Skype Insiders also running the latest version, and these interactions are limited to one-to-one conversations. Up next, we’d like to improve the UX around the invite to join a private conversation and bring the experience to the UWP client, says Microsoft.
Now you can participate in private conversation from a single device at a time, you can switch over the device anytime by sending a new private invitation but the received message tied to the device.
Deleting the conversation works same as like the regular chat and to end the private communication select “End Conversation” from chat header.
