Office 365 – Distribution List Migration Version 2.0 – Part 22

The end of basic authentication in Exchange Online…

Fall is now upon us and as we enter the month of October things are changing in Exchange Online. I hope that most of my administrative peers are aware that basic authentication in Exchange Online will be disabled October 1^st, 2022.

The preparations for this have been years in the making. I’m personally excited about the enhanced security this will bring to our customers. One of the preparation items was to prepare and release a version of the Exchange Online Management Module that no longer requires the use of basic authentication. Many administrators did not realize but even prior versions of the module that “supported modern authentication” were still leveraging basic authentication under the hood as part of the connection to Exchange Online.

Exchange Online Management Module version 3.0.0 is now published to the PowerShell gallery. With the introduction of this module administrators now have a fully modern authentication-based method of performing Exchange Online management through PowerShell. In addition, this module moves away from the legacy PowerShell infrastructure to new REST based commands. These new commands have the same look and feel without the issues that the legacy remote PowerShell infrastructure had.

Distribution List Migration module version 2.7 is now hard coded to require a minimum version of 3.0.0 to perform distribution list migrations. Administrators may upgrade to this version using the update-module ExchangeOnlineManagement command or install the module for the first-time using install-module ExchangeOnlineManagement.

Happy migrating!
