Script: Connect-365.ps1 – Connect to Office 365 services using remote PowerShell

I’m excited to announce the release of Connect-365! Back 2012, I put together a basic script with a GUI to simplify connecting to Exchange Online via remote PowerShell. I had never intended to make the script publicly available and it was just something I used myself. After a couple years I realized that it had been shared with so many colleagues and clients that I decided to clean it up and publish it on the TechNet gallery. Connect-EXO was born! Here’s a screenshot of the original first version:

Over time the script matured into what Connect-EXO is today. One of the challenges in the early version was that I used WPF for the GUI, this was problematic for older versions of PowerShell so I made the decision to port it to Windows Forms for backward compatibility. Forms is old and added a lot of bloat and since backwards compatibility is no longer a concern, I decided to move back to WPF. Connect-365 is essentially the next version of Connect-EXO, I renamed it so more accurately reflect it’s purpose and this will allow me to continue to maintain Connect-EXO.

Connect-365 features a GUI that will prompt for your tenant credentials and then connect to various Office 365 services using remote PowerShell. The built-in prerequisite checker will check to ensure that the correct modules are installed and provide a download link for those that are not.

The current version of the script allows connectivity to:

  • Exchange Online
  • Azure Active Directory (using v2 module)
  • Office 365 Security & Compliance Center
  • Skype for Business Online
  • SharePoint Online

This script will work natively in PowerShell 4.0+

There are no parameters or switches, simply execute the script: .\Connect-365.ps1

Execution Policy:
This script has been digitally signed and will run just fine under a “RemoteSigned” execution policy



  • Support Azure AD v1 and v2
  • Support for Exchange Online MFA (via module)
  • Derive SPO Admin URL
  • Auto-install prerequisites
  • Much more..

I have published it to the TechNet Gallery, it can be downloaded by clicking here…

    Cool stuff. Have you thought about running it through PSSharper (part of ISEsteroids) in ISE? It’s making a few suggestions.
