Basic Authentication – Remote PowerShell

From Microsoft Corporation
Technical Bulletin MC344868 · Published Mar 19, 2022

Message Summary

We’re making some changes to improve the security of your tenant. We announced in 2019 we would be retiring Basic Authentication for legacy protocols and in early 2021 we announced we would begin to retire Basic Authentication for protocols not being used in tenants. 

7 days from today we’re going to turn off Basic Authentication for Remote PowerShell in your tenant. Based on our telemetry, no-one is currently using Basic Authentication with Remote PowerShell in your tenant and so we expect there to be no impact to you. 

We previously communicated this change via Message Center: MC191153 (Sept. ‘19), MC204828 (Feb. ‘20), MC208814 (April ‘20) and MC237741 (Feb. ‘21) and you can always read the latest information about our plans to turn off Basic Authentication here.

We will send another Message Center post when we make the change. You may receive additional notifications if any other protocols could be affected.

How this will affect your organization:

Once this change is made, users in your tenant will be unable to access their Exchange Online mailbox using Basic Authentication and this specific protocol.

What you need to do to prepare:

This is for your awareness only. If you experience any issues, please follow your standard support processes.
