Connecting to all O365 services at the same time in PowerShell (Including Installation and Teams)

I often use scripts that uses cmdlets from different modules so I can use all sorts of data sets when handling my Office365 administration tasks. The problem is that I often found myself connecting to a specific service such as the Exchange services, only to need the security center moments later – or the MSOL Module right after. When reinstalling my laptop I decided to not bump into this anymore, mostly to just get rid of my annoyance.

After a short search online I’ve found that there already was a bit of an example here on the Microsoft docs website. Unfortunately this guide is outdated and does not included the newer Teams Module. It also does not automatically find the correct SharePoint URL. As I am quite lazy and never want to look things up I also added the functionality to find the correct URL and to download the right modules. Currently it connects to the following services:

Services

Service	Module Name
AzureAD (Graph)	AzureAD Module
AzureAD(MSOL)	MSOL Module (Legacy)
Teams	MicrosoftTeams(Beta)
Exchange Online	PSSession to Exchange Endpoint
Security & Compliance	PSSession to Protection endpoint
Sharepoint	Microsoft.Online.SharePoint.PowerShell
Skype for Business	SkypeOnlineConnector

The function has only two options; a -Disconnect in case you want to end the sessions cleanly, and a -Credentials option for passing the credentials. Both are optional. To make sure the Function is always available to me I’ve added it both to my VSCode Profile and my PowerShell profile by starting a PowerShell prompt in both tools and entering the following one-liner:

New-Item -Path $profile -ItemType File

This creates a file in your profile path. Any code you paste here will always be loaded on startup. Because I use a lot of functions I do not like posting my code directly here, instead I save my modules to a specific folder, and have it look in that folder for any functions that I add.

$MyFunctions = "C:\Posh\Functions"
write-host "Loading Functions" -ForegroundColor Yellow
Get-ChildItem "$MyFunctions\*.ps1" | %{.$_}
write-host "Done Loading functions." -ForegroundColor Green

This small piece of code looks in C:\Posh\Functions for all .PS1 files and loads these files as if I just run them as a script. This makes sure small functions which do not need to be an entire module on their own are loaded correctly. In C:\Posh\Functions I’ve saved the following script which I’ve called “Connect-Office365.ps1”

Script

function Connect-Office365 {
    param(
        [System.Management.Automation.PSCredential]$Credential,
        [switch]$Disconnect
    )
    if($Disconnect){
    Get-PSSession | remove-pssession
    Disconnect-SPOService
    Disconnect-AzureAD
    exit }
write-host "Checking Prerequisites" -ForegroundColor Green
try{
    Import-Module AzureAD -ErrorAction stop
} catch {
        write-host "Could not find AzureAD Module. Installing."  -ForegroundColor Green
        install-module -Name AzureAD -Scope CurrentUser -force
        Import-Module AzureAD -ErrorAction stop
        }
try{
     Import-Module MSOnline -ErrorAction stop
        } catch {
     write-host "Could not find MSOL Module. Installing."  -ForegroundColor Green
     install-module -Name MSOnline -Scope CurrentUser -force
     Import-Module MSOnline -ErrorAction stop
       }

 try{
     Import-Module MicrosoftTeams -ErrorAction stop
    } catch {
     write-host "Could not find MSTeams Module. Installing"  -ForegroundColor Green
     install-module -Name MicrosoftTeams -Scope CurrentUser -force
     Import-Module MicrosoftTeams
      }
try{
    Import-Module Microsoft.Online.SharePoint.PowerShell -ErrorAction stop
    } catch {
    write-host "Could not find Sharepoint Module. Installing"  -ForegroundColor Green
    Install-Module -Name Microsoft.Online.SharePoint.PowerShell -Scope CurrentUser -force
    Import-Module Microsoft.Online.SharePoint.PowerShell
    }
try{
    Import-Module SkypeOnlineConnector -ErrorAction stop
    } catch {
    write-host "Could not find Skype For Business Module. Installing"  -ForegroundColor Green
    Invoke-WebRequest "https://download.microsoft.com/download/2/0/5/2050B39B-4DA5-48E0-B768-583533B42C3B/SkypeOnlinePowerShell.Exe" -OutFile "$($env:TEMP)/SkypeOnlinePowerShell.exe"
    Start-Process "$($env:TEMP)/SkypeOnlinePowerShell.exe" -ArgumentList "/install /quiet" -wait
    Import-Module "C:\Program Files\Common Files\Skype for Business Online\Modules\SkypeOnlineConnector"
     }
if(!$Credential){ $credential = Get-Credential }
write-host "Connecting to AzureAD Module" -ForegroundColor Green
Connect-AzureAD -Credential $credential
write-host "Connecting to MSOL Services" -ForegroundColor Green
Connect-msolservice -Credential $credential
write-host "Connecting to Teams Services" -ForegroundColor Green
Connect-MicrosoftTeams -Credential $credential
write-host "Connecting to Exchange Online" -ForegroundColor Green
$exchangeSession = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri "https://outlook.office365.com/powershell-liveid/" -Credential $credential -Authentication "Basic" -AllowRedirection
Import-PSSession $exchangeSession -DisableNameChecking
write-host "Connecting to Security &amp; Compliance Center" -ForegroundColor Green
$SccSession = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri "https://ps.compliance.protection.outlook.com/powershell-liveid/" -Credential $credential -Authentication "Basic" -AllowRedirection
Import-PSSession $SccSession -Prefix cc
Connect-MicrosoftTeams -Credential $Credential
write-host "Getting initial domain for Sharepoint Online"
$InitDomain = (Get-MsolDomain | Where-Object { $_.IsInitial -eq $true }).name
$InitDomain = $InitDomain.Split(".")
$SharepointDomain = $InitDomain[0]
write-host "Connecting to $($SharePointDomain) Sharepoint"
Connect-SPOService -Url "https://$($SharepointDomain)-admin.sharepoint.com" -credential $Credential
$sfboSession = New-CsOnlineSession -Credential $credential
Import-PSSession $sfboSession -AllowClobber
}

And that’s it! the code above is a bit rough around the edges but that is because it is just a simple function I use for my own personal preference. To use it, all you have to do is type Connect-Office365 and there you go 🙂

If you encounter any issues or have questions, let me know! and as always, Be careful and happy PowerShelling!
