Microsoft is removing TLS 1.0 and 1.1 from Microsoft 365. This has been well flagged, but tenants might not understand the impact on PowerShell scripts which send email using the Send-MailMessage cmdlet and SMTP AUTH. In a nutshell, unless you force PowerShell to use TLS 1.2, attempts to send messages via Exchange Online will fail. It’s time to check those scripts and ,consider how to move away from SMTP AUTH and Send-MailMessage.
A reader asked how to find when Azure AD accounts received certain licenses. As it turns out, this isn’t as simple as it seems. PowerShell can tell use when user accounts are enabled with service plans, but to get dates for licenses (products or SKUs), we need to go to the Graph API, and those dates aren’t quite there yet. In any case, it’s an interesting question which deserves some exploration to see if we can find an answer.
Understanding how to create effective queries using the Microsoft Graph APIs takes some work, especially with some of the more complex filters used to refine the data returned by the Graph. In this article, we look at how filters using lambda qualifiers work and explore some examples of these qualifiers in use.
Anyone writing PowerShell code against Azure Active Directory probably uses the Azure AD module. In June 2022, Microsoft will deprecate the API underpinning the Azure AD module. Tenants who want to use PowerShell to create scripts to automate administrative processes will need to move to Graph API calls or use the Microsoft Graph PowerShell SDK. Either way, there’s a bunch of work to do to upgrade scripts.
