Create and setup a Microsoft Teams Room Device in Microsoft Office 365

I recently blogged about Microsoft Teams Room Devices, my setup and experience with it. In the second article I mentioned my Office 365 setup and the licenses I use.

So, someone asked me to publish the Office 365 related part, and of cause I used PowerShell to setup everything.

<#
      .SYNOPSIS
      Create a Microsoft Teams Room Device in Office 365

      .DESCRIPTION
      Create and setup a Microsoft Teams Room Device in Microsoft Office 365

      .NOTES
      Review the variable here.

      You must be connected to the following Services:
      - Exchange Online
      - MSOL (Not AzureAD!)
      - Skype for Business Online (Not Teams!)

# Display Name of the Room
$RoomName = 'Your-Teams-Room'

# Alias of the Room (For the UPN, SMTP, and SIP Address)
$RoomAlias = 'YourTeamsRoom'

# Keep this safe
$RoomPassword = 'YourSuperSecretRoomPassword'
<#
      At the moment, the password for a room/resource will never expire!
      So keep this in a safe place. And there is no second factor (MFA).

# The Domain for the UPN, and the SMTP address
$RoomDomain = 'contoso.com'

# The Response text for meeting requests
$RoomAdditionalResponse = 'This is a Microsoft Teams Team Room'
<#
      Basic HTML is supported here!
      This text will be in the meeting respoinse mail, so use it as a info or teaser
#>

# The ALIAS of the license to apply.
# In this case it is the MEETING_ROOM License in the tenant with the name contoso
$RoomLicence = 'contoso:MEETING_ROOM'
<#
      The license must be availible (Buy it before create the room)

# We need one User that we use to find the SIP Registrar Pool (For Skype for Business and Teams SIP handling)
$CsOnlineUser = 'john.doe'

#region AutomatedStrings
# Build some strings
$RoomUserPrincipalName = ($RoomAlias + '@' + $RoomDomain)
$CsOnlineUserTemplate = ($CsOnlineUser + '@' + $RoomDomain)
<#
      I use the same domain for the UPN and the SMTP/SIP address,
      and I highly recommend you to do the same!

As always, there is also a GIST available for this!

Please note: This is nothing fancy, it’s just the initial part to create a basic Room system in Microsoft Office 365.

Also keep in mind, that nearly everything is hardcoded and that there is no fancy error handling.
