The following features are available in the Public Developer Preview as of August 25, 2017.

Apps in Microsoft Teams

Apps in Microsoft Teams allow you to make your service available to users through a single Teams App package, which includes bots, tabs, connectors and compose extensions.

Discover Apps gallery

The Discover Apps gallery provides a listing of all apps available in Microsoft Teams spanning various categories. Developers can get apps in by submitting their apps to the Office Store.

Compose extensions

Compose extensions make it easy for users to query for information from your service and post them into conversations in the form of rich cards.

App notifications

App notifications allow apps to send messages using the Bot Framework without having to implement a conversational bot. It also enables them to mark messages as important and to post messages to the activity feed.

Actionable connectors

Actionable connectors use the new Actionable Message card type within Microsoft Teams that allow users to interact with connector cards.

Bot message updates

Bot messages can be updated after they have been delivered, enabling apps to always show up-to-date state in their messages as new information becomes available.

Cloud Connector Edition Upgrade Issues

Cloud Connector Edition

Since i was facing some isssues last time with upgrading our company Cloud Connector Edition it’s a good thing to keep old installers (check below for Archive).

We had the CCE 1.4.2 version running, due to some accounting issues the upgrade to 2.0.0 never has started. You can use Set-CcCredential -AccountType TenantAdmin to set the new global admin account. (Global admin role required for 1.4.2, from 2.0.0 and newer Skype Admin role is required) So after setting the right O365 account i tried to start upgrading the appliance.

Because of the release 2.0.1 the Start-CcDownload cmdlet started downloading the 2.0.1 installer. Started cmdlet Install-CcAppliance -Upgrade and after 1,5 hour the setup stopped with all kind of errors, no sql installed on Edge, certificate issues and so on.

Let’s Encrypt and Skype for Business

Let's Encrypt Skype for Business

For my home lab I’m using the free certificates from Let’s Encrypt (Let’s Encrypt is a free, automated, and open Certificate Authority).

The certificates from them have 1 big limitation, they are only valid for 3 months but you can renew them “almost” automatically.

As explained In my blog last week about “Skype for Business environment running with just one public IP” I’m running my Reverse Proxy with IIS ARR (Application Request Routing). I’ll try to explain how to request and assign the free certificates for your homelab.

What’s fixed in Cloud Connector Edition 2.0.1

Cloud Connector Edition

In Cloud Connector Edition 2.0.1, the following fixes were made:

Restarting Virtual Machines sometimes caused the service to stop if the restart order determined by Hyper-V was incorrect. This has been fixed.
Calls for download security checks in remote PowerShell sometimes caused calls to the New-CsOnlineSession cmdlet to fail. This issue has been fixed.

During automatic updates, switching to a new version sometimes caused the running version to fail. This issue has been fixed

You can download the new Cloud Connector Edition 2.0.1 is now. If you have not yet upgraded to 2.0.1, You can find the installation file at https://aka.ms/CloudConnectorInstaller
