Connecting to the Microsoft Graph Using the PowerShell SDK

Tony Redmond — Thu, 23 Sep 2021 13:11:30 +0000

The Microsoft Graph SDK for PowerShell exists to help developers use Graph API calls from PowerShell. It works, but like anything in life, there's a right way to connect and use the SDK and a wrong way. In this article we explore topics like how to connect to the right tenant, how permissions are managed (or not), and why running Graph SDK cmdlets interactively isn't something you should do in production. Good as the SDK is, Microsoft has some big issues to solve to address some obvious security issues.

Microsoft to Retire Old Exchange Admin Center in Office 365 Next Year

Tony Redmond — Tue, 14 Sep 2021 06:46:00 +0000

Microsoft plans to retire the now-decrepit and very old EAC on September 1, 2022. The old console has hung on too long, perhaps because Microsoft hasn't progressed the development of its replacement as quickly as they could have since its 2019 debut. Although Microsoft claims that the new EAC reached feature parity with the old some time ago, any examination of the two consoles proves that this is not the case. With that in mind, it seems like Microsoft has some work to do to make everything ready for the big retirement date in 2022.

Tony Redmond — Thu, 15 Jul 2021 04:16:00 +0000

Converting PowerShell scripts from the old API to the new isn't particularly difficult if you have ever worked with the Graph before. As always, the devil is in the detail, but persistence and some mild swearing should be enough to get scripts over the line. This article explores how to use the new API to fetch and report details of service incidents.

Upgrading PowerShell Scripts with Azure AD Cmdlets to Use Graph API Calls

Tony Redmond — Wed, 07 Jul 2021 05:18:00 +0000

Microsoft has announced that they won't support the Azure AD Graph after June 30, 2022. This means that the Azure AD PowerShell module won't be supported either. With that in mind, it's probably a good idea to think about how to upgrade scripts to use Graph API calls instead of Azure AD cmdlets. In this article, we take a script created to count members in distribution lists and convert it to use the Graph. As it turns out, the Graph bit is easy. It's all the housekeeping beforehand that takes the time.

Creating Personal Contacts in User Mailboxes with PowerShell and the Graph

Tony Redmond — Tue, 15 Jun 2021 08:08:00 +0000

An earlier article explained how to create organizational contacts in user mailboxes with Graph API calls. This article builds on that idea with three improvements. First, we select target mailboxes for update by looking for those added in the last month. Second, we allow any mail-enabled recipient to be added as an organizational contact. Third, we incorporate some code to check if a contact already exists in a mailbox. Like anything with PowerShell, this code can be improved..

Moving on from Send-MailMessage: Sending Email from PowerShell using the Graph API

Tony Redmond — Tue, 08 Jun 2021 07:22:00 +0000

Many PowerShell scripts use the Send-MailMessage cmdlet to send mail. That's fine, but if you want to remove basic authentication to improve tenant security, you need to stop using Send-MailMessage. One solution is to move to use the Graph API SendMail call. This works fine, but it creates some new security issues that need to be thought through. In this article, we explain how to use the Graph to send email and some of those security considerations to ponder.
