Hi,
Sorry, starting October 31, 2019, the Skype channel will not accept new requests to publish bots. This means that you can develop bots using the Skype channel, but the bot will only be available to 100 users. You will not be able to publish the bot to more users. The current bots on Skype will work without interruption.
If you have a running bot before that day, you can use it. But for now new bot can not expand to more than 100 users.
Please let us know your scenario if you feels the skype channel is critical to you, we can re view it to see how we can help.
Thanks.
Regards,
Yutong
