Installation of Exchange 2016-Enabling Instant Messaging on Outlook Web App
Equipped with Skype for Business Server correctly setup and configured, you may then start to configure Outlook Web App. The primary step in that process is to enable instant messaging present on all your Outlook Web App virtual directories on your front-end servers. (There is no requirement to enable instant messaging for the virtual directories on your backend servers. It is recommended that you do not enable instant messaging on your backend servers.) Login to your Exchange Server and begin Exchange PowerShell, and then execute the following command:
Get-OwaVirtualDirectory | Set-OwaVirtualDirectory -InstantMessagingEnabled $True –
In case it is successful, you must see this (ignore making a new session message, as I had Exchange PowerShell open to long)
Now we require confirmation in case we have any certificate assigned for UM service. In Exchange PowerShell execute the following command:
Get-ExchangeCertificate | select services
As you might observe, we do not have any Certificate allocated to UM service. Login to ECP ( https://mail.domain.com/ECP ) and navigate surfing to Servers – and Edit your Exchange server:
Navigate to surf over the Unified Messaging and alter UM Call Router settings and UM Service settings to TLS mode. Select “Yes” to confirm
Click on Certificate present on the top menu and edit your choosen certificate
Now, Click on ervices and then check for both UM services and yes to confirm.
Over your Exchange server, open services and restart both UM services.
In Exchange PowerShell execute the following command to get thumbprint of your UM certificate:
Get-ExchangeCertificate | select services,thumbprint
Make a note of the Thumbprint which has been assigned UM services.
