Connecting to Office 365/Exchange

Posted on August 31, 2015 by Michel de Rooij

Last update: Version 3.17, September 8, 2023

Almost 3 years ago, I wrote an article on how to enhance the PowerShell Integrated Scripting Environment, or ISE. That seemed adequate for the Exchange admin back then, who would mostly connect PowerShell sessions to their on-premises environment, and occasionally a bit of Exchange Online.

Fast forward to 2015, most modern Exchange administrators not only require a connection – if any – to their Exchange on-premises environment, but likely to one or more of the Office 365 services as well, including Exchange On-Premises, Azure Active Directory, Exchange Online Protection, Microsoft Teams, Skype for Business Online, SharePoint Online, Azure Information Protection or Compliance Center.

All these services use a different PowerShell session, use a different endpoint FQDN, and in some cases require a locally installed PowerShell module. Likely common denominator is the credential used to access each of these services. So, tired of re-entering my credentials every time when switching from Exchange Online to Exchange Online Protection, I created a script with a set of functions to allow me connect to each individual Office 365 service or Exchange Online:

Connect-AzureActiveDirectory: Connects to Azure Active Directory
Connect-AIP: Connects to Azure Information Protection
Connect-ExchangeOnline: Connects to Exchange Online
Connect-SkypeOnline: Connects to Skype for Business Online
Connect-EOP: Connects to Exchange Online Protection
Connect-ComplianceCenter: Connects to Compliance Center
Connect-SharePointOnline: Connects to SharePoint Online
Connect-MSTeams: Connects to Microsoft Teams
Get-Office365Credentials: Gets Office 365 credentials
Connect-ExchangeOnPremises: Connects to Exchange On-Premises
Get-OnPremisesCredentials: Gets On-Premises credentials
Get-ExchangeOnPremisesFQDN: Gets FQDN for Exchange On-Premises
Get-Office365Tenant: Gets Office 365 tenant name (SharePoint)
Set-Office365Environment: Configures Uri’s and region to use
Get-TenantID: Returns TenantID using previously used credentials
Update-Office365Modules: Updates supported Office 365 modules
Report-Office365Modules: Report on known vs online module versions

Note that functions and credentials used in the script are global, and in principle only need to be entered once per shell or ISE session. If you need different credentials, call Get-Office365Credentials again. User interaction is a very basic (Read-Host), but it does the job. The script will also detect if any PowerShell module supporting Multi-Factor Authentication is installed. If so, you will be prompted if for using MFA when authenticating to workloads such as Exchange Online, Azure Active Directory, Microsoft Teams, Skype for Business Online or SharePoint Online.

Requirements
During initialization, the script will detect the modules which are required for certain Office 365 services. When not installed, it will notify you, and provide a link where to obtain the PowerShell module. The related Connect function will not be made available. PowerShell is required to run this script, which is tested against version 5.1 (but should work with lower versions down to version 3).

Usage
The functions are contained in a script called Connect-Office365Services.ps1. You can call this script manually from your PowerShell session to make the functions available. However, more convenient may be to have them always available in every PowerShell or ISE session. To achieve this, you need to edit your $profile, which is a script which always starts when you start a PowerShell or ISE session. By default this file does not exist and you need to create it, including the path. Also note that the files for PowerShell and ISE are different, Microsoft.PowerShell_profile.ps1
and Microsoft.PowerShellISE_profile.ps1 respectively.

Now, of course you can copy and paste the functions from the script file to your own $profile. Better is to call the script from your $profile, as this allows you to overwrite the Connect-Office365Services.ps1 with updates. To achieve this, assume you copied the Connect-Office365Services.ps1 in the same location as your $profile, for example C:\Users\Michel\Documents\WindowsPowerShell. You can then make PowerShell and ISE call this script by adding the following line to the $profile scripts:

& “$PSScriptRoot\Connect-Office365Services.ps1”

Now when you start a PowerShell session, you might see the following:

This shows the default environment is targeted (AzureCloud), the Exchange Modern Authentication PowerShell module as well as other modules mentioned in the example are installed. When online version checking is enabled (OnlineModuleVersionChecks variable), a check will be performed against the online repository, e.g. PSGallery, and outdated modules will be reported, like the Skype for Business Online module in the example. It’s also possible to automatically update modules setting the variable OnlineModuleAutoUpdate.

When you load the script from ISE, it will show something similar. However, it will also detect ISE and make connect functions available through the Add-On menu:

Notes
Customize this script to your liking. Note that for updating modules, you need to have administrator permissions on the local system.

Download
You can download the script from GitHub.

Hi Michel,
Your script has been a great time-saver for me. I just added the latest version (5/30/17) to my profile and it keeps crashing with the ‘404’ error whenever it tries to load and connect to SkypeOnline. Happens with both the ‘connect-office365’ as well as ‘connect-skypeonline’ calls. The ‘all services’ command doesn’t go any further when it fails at Skype. I’m looking forward to seeing what we can do with the MFA side of this once I get past this. If I’m doing something wrong, pls advise. Thanks!

One other minor issue, to get the ADAzurePreview module to load, I had to use the following command.

Hi Michel, thanks for the script! I am now using it with the MultiFactorAuthentication and what I run in to is that when I run the connect function to connect to all, you do not immediately set the $global:Office365CredentialsMFA and thus the AzureAD connection is tried with the basic credentials object. I updated it to initially call that Get-Office365Credentials function that sets the $global:Office365CredentialsMFA, and then that works.

What is a bit annoying with that MFA in Powershell is that for every connection that you make you need to authenticate again, and as far as I see the compliance-center powershell URI does not (yet) support MFA? Is that correct?
Thanks for sharing!

  Thanks for the heads up. Unfortunately, tokens cannot be reused across connecting to workloads atm. And yes, standard PowerShell remoting does no support ADAL (thus MFA), e.g. ‘legacy’ Exchange Online or Compliance Center.

  Basic authentication can be fed credentials, Modern Authentication with MFA or ADFS not, and tokens between workloads can not be shared (each workload different dialog). Plus side, when using UserPrincipalName with Exchange w/MA for example it will reuse the current token, so you will see the dialog appear briefly.

  Connect-MSolService is the msol connect cmdlet; it doesn’t reuse credentials used to connect to other services (hence why you need to use the helper functions provided). Note that MFA might require reauthenticating as well, as tokens are not shareable for all workloads at the moment. Finally, not having New-IPSSession indicated you don’t have the Exchange Online MFA-enabled powershell module installed; you can’t connect to the SCC anymore using old-fashioned remote PS.

    Whats weird is I have the Microsoft Exchange Online Powershell Module installed and I can connect to Exchange online using Connect-EXOPSSession and can connect to the compliance center using Connect-IPPSSession and both work fine.
    
    The issue i am facing is when using the script and “Connect-ComplianceCenter” I am getting the “New-IPPSSession : The term ‘New-IPPSSession’ is not recognized” error.
    
    It prompts me for credentials and MFA and after approving the MFA I get that error.

Looks like an extra URL in the Teams definitions are hanging it up.

  It seems to do that when you installed the GA and test modules side by side. Please check out v2.15

In 2.20 the Connect-ExchangeOnlinev2 doesn’t work for basic authentication. Looks like the connection string has -ConnectionUrl instead of -ConnectionUri and -Session instead of -PSSession. I fixed those and it works great now! Thanks as always for the awesome script.

Hi Michael,
The latest version of the script I copied from GitHub doesn’t appear to have a variable named OnlineModuleAutoUpdate. I assume this was replaced with the Update-Office365Modules command?

  Yes, functionality has been replaced (per v2.10) by Update-Office365Modules, as feedback suggested people don’t want the ‘delay’ every time they start a session (and thus never used it). If you want it, you could call Update-Office365Modules in your profile after loading the Connect helper functions.

Hey Michel, I’m unable to get the latest version (2.25) of the script to recognize that the Skype for Business Online module is installed. I uninstalled and reinstalled it with no change and Get-Module reports that it’s installed.

Any ideas? Thanks!

      The SkypeOnline module is an odd beast nowadays with it’s MSI install and being not integrated in the PowerShell module ecosystem (properties missing). Functionality is also available per recent Teams module (New-CsOnlineSession), and I think the installable SkypeOnline module might be out its way out, so you might want to move away from that anyway.

Hello Michel,

Whenever I try to connect to MSTeams and select “Y” to use Modern Auth, I keep getting a popup window after typing my username/password stating my Tenant ID isn’t found. This may happen if there are no active subscriptions for the tenant…

Request Id: 144fa700-53bd-4f23-ae61-d5024ec04301
Correlation Id: 6033fdde-d7ba-4086-920f-7068c6794007
Timestamp: 2020-06-18T10:29:46Z
Message: AADSTS90002: Tenant ‘xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx’ not found. This may happen if there are no active subscriptions for the tenant. Check to make sure you have the correct tenant ID. Check with your subscription administrator.

Any thoughts or what am I doing incorrectly?

  No. You used to require license or team membership to connect, don’t know from my head if that still applies.

    Umm ok. What’s odd though is if I just type Connect-MicrosoftTeams in the PS ISE window, I get the popup box, type username and pword, and it connects fine.

From version in November 2022 to the latest version, no longer populates the exchange on-premise options – an earlier version I have (Version 2.71 April 29th, 2021) works as expected.

For many versions now including the latest 3.16 when I run Report-Office365Modules it states the Az module not found. I have uninstalled it and re-installed it using Install-Module Az -Scope AllUsers -Repository psgallery -AllowClobber -Verbose.
It installs ok but Report-Office365Modules still complains it is not found.
It is a minor thing but I’d like to fix it. Any ideas?
