I have some trouble when I try to use the Exchange powershell commandlet : New-MailUser (doc). More specifically, it's using a SecureString that fails.
My problem is that it works well on my windows dev env, but once it's executed on a Linux, it won't. (both powershell 6. Even tried the 7)
I got the following error :
Session key not available to encrypt secure string
I suppose it's a connection type issue (SSL/TLS) (learn from https://www.cloudflare.com/learning/ssl/what-is-a-session-key/ )
Executed commands :
$session = New-PSSession -ConfigurationName:Microsoft.Exchange -Authentication:Basic -ConnectionUri:https://outlook.office365.com/powershell-liveid/ -Credential $credentials -AllowRedirection
Import-PSSession -Session $session
Invoke-Command -Session $s -ScriptBlock { New-MailUser -Name "Ed Meadows" -ExternalEmailAddress [email protected] -MicrosoftOnlineServicesID ed@tailspintoys -Password (ConvertTo-SecureString -String 'P@ssw0rd1' -AsPlainText -Force) }
I don't know how to work around this, or what I did wrong...
Any enlightened people to help?
