This meant it was now possible to connect to Exchange Online with unattended scripts that no longer passed a username and password, and therefore eliminating the issue where MFA is required upon authentication. Given the challenge as described above, I was extremely excited when Microsoft released the EXO V2 2.0.3 module for public preview in July 2020 where it introduced certificate based authentication. Microsoft originally had plans to disable basic authentication in 2020 but delayed it indefinitely.

As such, many administrators continued to use basic authentication or modern authentication with accounts without MFA enforced to work around the issue, which leads to vulnerability issues. The introduction and enforcement of modern authentication and MFA meant attempting to run unattended scripts would no longer work because it would require an administrator to interactively enter credentials and authenticate with the 2 nd authentication. I very carefully made each commit standalone and annotated.Those who have worked with Exchange Online PowerShell for a while will know how much a challenge it was to move from basic to modern authentication with MFA for unattended scripts that are scheduled to run non-interactively.

Connect-ExchangeOnline is now idempotent, and will not start a new connection if you already have one unless you specify -Force or the connection is in a broken or disconnected state.

Extensive cleanup of unnecessary module importing to improve performance and reduce verbosity.

No longer pollutes your session with a bunch of _EXO_ global variables!.This can drastically improve the login performance time. -CommandName parameter added to Connect-ExchangeOnline to allow you to only import a subset of commands.You can specify $_EXO_SUPPRESSBANNER=$true in your profile or session to remove the 'MOTD' from Connect-ExchangeOnline.-ShowBanner is now -HideBanner to reflect proper use of parameters.

This is currently only tested with 1.0.1 at the moment. psm1 over the top of your existing ExchangeOnlineManagement module. A rework of the Exchange Online Management Module as much as possible to use Powershell best practices To UseĬopy the.
