Microsoft Teams - Install Preview/Prerelease Powershell Module

Microsoft Teams has a preview/prerelease version of their powershell module available which has some commands that aren't contained in the general/public release.

If you wish to install the prerelease module, you can use the command below to do so

Install-Module -Name MicrosoftTeams -AllowPrerelease -force

You may need to restart your powershell session and import the module again to get the required cmdlets.

If you get an error saying the 'allowprerelease' argument isn't recognized, then run the below commands ot update the PackageManagement and PowershellGet modules

Install-Module -Name PackageManagement -Repository PSGallery -Force
Install-Module -Name PowerShellGet -Repository PSGallery -Force

Restart your powershell session then run the install-module command again and it should complete successfully.

Powershell - a parameter cannot be found that matches parameter name 'AllowPrerelease'

Sometimes when installing powershell modules, you may wish to utilise pre-release or preview versions of packages. Depending on what version of powershell you have installed, you may get an error message like the one below when attempting to install preview/prerelease packages;

Install-Module : A parameter cannot be found that matches parameter name 'AllowPrerelease'.

At line:1 char:37

To fix the problem you need to force an update of a couple of Powershell modules - namely PowershellGet and PackageManagement. 

Run the commands below from an elevated powershell command prompt;

Install-Module -Name PowerShellGet -Repository PSGallery -Force
Install-Module -Name PackageManagement -Repository PSGallery -Force

Exit/close your Powershell window/session then re-open and run the install-module command again - it should now complete successfully

Exchange 2010 New Install - Nothing Showing Under Microsoft Exchange On-Premises

After installing Microsoft Exchange Server 2010 onto a Windows Server 2012 R2, nothing was showing under the Exchange Management Console after expanding "Microsoft Exchange On-Premises".

Everything under "Exchange 2010 Organizational Health" was showing as "Unavailable"



When selecting the option to "Collect Organizational Health Data", the below error occurs stating "MMC has detected an error in a snap-in and will unload it"



To resolve this issue you need to install the latest Service Pack (SP3) for Microsoft Exchange Server 2010 - available from the following URL:

You can then install Update Rollup 14 for Microsoft Exchange Server 2010 SP3 from the following URL:

As you can see below, once SP3 has been installed, the Configuration options are now available/showing under "Microsoft Exchange On-Premises" after the updates are installed
