Hi @The_Exchange_Team ,
We are getting the following messsage in O365 output stream when remote powershell is used. This is breaking our automation scripts. Please let me know how to stop it from occurring.
=============================================================
New update available!
You are using an older version of Exchange PowerShell cmdlets which may be using (soon to be deprecated) Basic authentication.
Please install version 2.0.6 of the ExchangeOnlineManagement module to upgrade to the latest version of cmdlets, which are REST based, more secure, reliant and performant than the remote PowerShell cmdlets that you are currently using.
For more information on the latest cmdlets released, visit: https://techcommunity.microsoft.com/t5/exchange-team-blog/exchange-online-powershell-v2-module-preview-now-more-secure/ba-p/2922946
To download the latest version of the module, visit https://www.powershellgallery.com/packages/ExchangeOnlineManagement/2.0.6-Preview5

Thanks,
